This problem has been extremely intermittent.
When playing RetroArch on Windows 10 (currently on latest nighty as of the last hour) everything starts out working great. I can open the RA menu, change shader options, etc, etc.
However, every several or so times I open the RA menu and go back to the game… I suddenly can’t get ‘back’ into the menu. All hotkeys appear to be disabled. I can’t even use the keyboard’s F1 to pull up the menu.
I can play just fine, controller inputs all work, but I have to Alt+F4 to quit RetroArch.
I’ve tried reinstalling RA from scratch, updating to the latest build (I’ve done this several times over the last couple months at least) double-checked I have nothing set to disable hotkeys in the input settings…
This has been going on for months at least, but it’s been so intermittent that at times I thought my update attempts fixed it. Except I’m trying to edit a shader-preset now, and going in and out of the RA Menu and I keep having to Alt+F4 in the middle of editing and testing the shader line…
I’m not sure what else to check though.
