Lately, when I try to play GZDoom, it messes up and registers any keystroke that opens the main menu twice. Meaning that pressing escape makes it open and immediately close. Anyone got any advice?

Hi! We're a fairly diverse plural system with various origins and interests! ADHD, autism, likely BPD. Uhm... Yeah, gonna work on this a bit more soon?

I saw this on my bookmarked tabs. I've had this problem before and it was because I use the windows ime and it would often end up in JP text mode in the game, so I'd have to switch it to ENG mode in order for the effect to stop. Dunno your own setup and stuff but hopefully that helps get an idea of where to start looking for the problem!
That seems to be it. Will have to be careful about that in future.
