So I was playing online yesterday for the first time (luckily on a pub, so none of you all think I'm THAT bad) and I was hitting v, the button I use for voice comm in TF2, to try and talk, but nobody was hearing me. so next time I was waiting to spawn, I went into my settings and it appeared to be unbound. So I set it to v, and was able to talk, but then as soon as I was able to spawn, I wasn't able to move my spawn marker. I went back into the options, and somehow all my movement keys were unbound too... I reset all of them manually, was able to move, but then when I tried to attack, my clicks weren't registering either. I went to the menu, hit 'restore defaults' and everything worked, including voice comm (albeit as c not v), which had appeared unbound before. I figured everything was fine, only it's still reading 'UNBOUND' in the little info boxes that try to tell me how to do a different infected's moves. The clicks work, but I get this huge picture of a button in the middle of my screen which is kinda irritating. Anyone else ever have this happen? Any suggestions or ideas as to what might have caused any of it?
