37. Troubleshooting¶
When I start SeligSIM, a black window comes up, stays black, and nothing happens (rare case).
My mouse pointer (cursor) is hidden, i.e., I cannot see it on the screen.
In the Transmitter Selection window, I click to calibrate and get the popup “Cannot Calibrate”.
When I try to fly in SeligSIM, the aircraft makes sound but does not move.
When I try to fly in SeligSIM, the aircraft will not move and the propeller turns slowly.
I would like to go back to the default install settings used in the Options menu.
What controls does my current aircraft have? How do I get to the Flight Manual?
My transmitter sticks or switches do the wrong thing.
How do I get back to a previous screen?
How do I pick a different aircraft, flying site, etc.?
I typed in a number, but the old one came back.
How can I get help when I am running the simulator?
How can I get help, while flying?
The simulator stutters during flight when using third-party security software like Webroot.
- When I start SeligSIM, a black window comes up, then disappears, and then nothing else happens. Or my screen flashes.
Download and install the latest graphics card driver for your computer, e.g., from AMD, Nvidia, or Intel.
- When I start SeligSIM, a black window comes up, stays black, and nothing happens (rare case).
This might be caused by the default window mode used by the sim on startup. Use your file editor to open the ‘options.txt’ file here:
C:\SeligSIM 2026\Options\options.txt
Find the line: “AutoFullscreen” and set the value to “0”, which is Auto Fullscreen OFF. [When the simulator is first installed, it uses AutoFullscreen=1 (ON).] Save the file and restart the simulator. This issue is rare and last happened on a system with these specifications: Windows 10 Pro, Build 19045, NVIDIA GeForce GTX 1070, Nvidia drivers from 10/29/2025.
- The colors look too dark.
For years the sim looked washed out on Nvidia graphics, and some users installed a Reshade filter to fix it. SeligSIM 2026 has the fix built in. If you installed Reshade for an earlier version, disable its effects or uninstall it, or the picture will be too dark.
- My mouse pointer (cursor) is hidden, i.e., I cannot see it on the screen.
On some systems (e.g., with Intel Graphics), if you use mouse “pointer trails,” that can cause the mouse pointer (cursor) to be hidden on the SeligSIM screen. Turn off pointer trails. You can turn it OFF from your Windows Control Panel. Find the Mouse Properties screen and uncheck “Display pointer trails.”
Mouse pointer trails unchecked.¶
- In the Transmitter Selection window, I click to calibrate and get the popup “Cannot Calibrate”.
The “Cannot Calibrate” popup appears if you click to calibrate, but do not have the proper USB interface selected on the previous Fly Screen. Go back to the Fly Screen and click on USB Interface and select an interface that is connected to your PC. Reselect the airplane. [Select the proper transmitter (if the wrong transmitter icon is shown).] Then return to the Transmitter Selection window to calibrate the newly selected USB interface. For reference, the popup warning that you see is this below.
- When I try to fly in SeligSIM, the aircraft makes sound but does not move.
This is also the answer to: “When I try to fly in SeligSIM, the aircraft will not move and the propeller turns slowly.”
The aircraft is being reset continuously because a switch on your transmitter has been assigned to control
Reset-To-HomeandReset-In-Place, and the switch is not in the right position for your setup.If you mapped your controller in the Mapping window, look at the Reset-to-Home / Reset-in-Place row (row 2). It should be fed by a 3-position switch, or by two buttons, so that it rests in the middle. A single button or a 2-position switch on that row will hold a reset. Fix the row, or Undo it and use the keyboard for resets.
If you calibrated in the Transmitter Selection window and did not move the reset-in-place and reset-to-home controls during calibration, then your controller can “send” a constant reset signal to the simulator. In that case, the airplane will not move and the propeller will turn slowly. The solution is to recalibrate and when you get to the point of moving the reset controls, be sure that you have a three-position switch assigned to it (or a combination of two, two-position switches). The reset slider during calibration should be movable to: low, middle, and high.
Finally, another possibility is that you have the reset switch on your transmitter in the high or low position. That will “send” a constant reset to the simulator and the airplane will not move while the propeller turns slowly. Move the reset switch to the other position.
There is actually “a last resort”. You can use the SeligSIM Power Tools program to turn off the controller reset functionality. Find that setting in the “Controller Options” section of the Power Tools. Checking the box there will disable it. Then to reset the airplane after a crash, use the keyboard to reset and/or allow the automatic reset to reset the airplane.
- When I try to fly in SeligSIM, the aircraft will not move and the propeller turns slowly.
See the answer for: “When I try to fly in SeligSIM, the aircraft makes sound but does not move.”
- I would like to go back to the default install settings used in the Options menu.
Follow these steps:
To reset the options back to the default install settings, start SeligSIM.
Go to Options | Messages.
Click on the box for Use Default Options Upon Shutdown.
Exit and restart SeligSIM. Note: This will restore the sim settings to those when originally installed. This will not, however, remove or change any edited aircraft or transmitters or change the calibration of your USB Interface.
- What controls does my current aircraft have? How do I get to the Flight Manual?
Depending on what you’re flying, see the flight manual for airplanes. To jump right to your aircraft, click on the Flight Manual button in the sim from the Aircraft Selection window. The same Flight Manual button is on the Single Pilot Freestyle window. While flying,
Left Shift+Iopens the Flight Manual panel, built from your own controller.
- My transmitter sticks or switches do the wrong thing.
If you mapped your controller in the Mapping window, open it from the Main Menu and click Show A/C. Move each control and watch what moves on the airplane. Fix the row that is wrong (Rev to reverse it, or drag the right control onto it). Otherwise, recalibrate your transmitter.
- How do I stop flying? (stop a flight session)
At the top left of your keyboard, press the
Esckey.
- How do I get back to a previous screen?
Click on Back, usually at bottom left. Or, at top right, click on Return to Main Menu.
- How do I pick a different aircraft, flying site, etc.?
Click on the picture of what you want to change. Or, at left, click on the word of what you want to change. Or type a letter,
Afor airplanes,Dfor flying sites,Sfor sun/sky,Wfor winds, and a quick search opens for that item. Type a few letters of the name and the list narrows as you type.Up/Downbrowse,Enterselects,Esccancels. If you have already clicked one of the panes,Fopens the quick search for that pane. Inside any of the selection windows (aircraft, flying site, sun/sky, wind, transmitter),Fsearches that window’s list the same way.
- I typed in a number, but the old one came back.
Most numbers have a range of allowable values. Invalid numbers, e.g., -10 lb for aircraft weight, are ignored. The previous value is then used.
- How can I get help when I am running the simulator? (help from this user manual)
When you are running the simulator, to get online help for whatever window you are in, at top right click on the green question mark button, i.e., this:
- How can I get help while flying?
Press the
/key (same key as “?”). Do not hold down shift to actually type “?”. Just press the key with the question mark on it. The Keyboard Shortcuts window opens. It is built from the sim’s own key bindings every time it opens, so it is always current. Type a word to filter it. Press/orEscto close it. If you cannot read while flying, also pressPto pause the flight. PressPagain to resume flying. The menu bar at the top of the screen also shows the key for every item. See the key commands chapter.
- The simulator stutters during flight when using third-party security software like Webroot.
Add the simulator to your security software’s exclusion list.
For Webroot: Open SecureAnywhere => PC Security => Block/Allow Files => Add File => Select the simulator .exe file (SeligSIM.exe) => Set to “Allow”.
