ALT F9 now freezes the Editor - Problem Solved

[IckyAtlas]

The ALT F9 key function allows to delete the terrain map so as to have all your objects icons, links etc. visible on a black background.

I used this function a lot and it did works some time ago before multiple updates. I recently needed this function as I am working on my missions and it does not work anymore. It immediately freezes / crashes the editor. I did multiple testes and it does not work. The key F9 alone does work by switching between 2D and 3D view.

I use windows W11 - Version 25H2, and Nvidia RTX 4090 with latest drivers 610.47. The editor is displayed on a 43 inch screen in 4K.

You must kill the editor task in the task manager to get out after it freezes.

My question here, is this a bug or has the Key setting changed for this function ?

Alt  F9 works for me as usual. Same with F9 and Ctrl F9.

Switching to this mode with the black blackground works (but I am not working in this mode).

Thanks, this means it is a local problem.

After some search I found the solution.

I was using my Logitech keyboard in a mode where to address the keys F1 to F12 you must first type the Fn+Fx key combination.

So if you need the Ctrl+F2 or Shift+F3 command, then I had to type Ctrl+Fn+F2 or Ctrl+Fn+F3. This works well without issue for all the commands but with Alt+F9, that is Alt+Fn+F9 it did crash the editor.

So I had to modify the keyboard's parameters so that the keys with the Functions would first act as function keys.

Once this was done I tested it and when typing the Alt+F9 I got the NVidia Shadow Play recorder activated, which comes in precedence to the Editor. So that key combination was captured by NVidia Shadow Player. I changed the parameters of that command to Alt gr+F9 to avoid interference with the editor.

And now the Editor reacts properly and it works perfectly.
