So I go into a mod pack from the technic launcher and I play single player, or any server, then go forward. After that, I can't do anything. I mean that I hit W and after 2 seconds i can't hit WASD E or T or 123456789 or anything i can't even click Esc i have to do COMMMAND+Q (mac) to go to home screen. Its not a problem with my keyboard because my keys work on everything else. See: The quick brown fox jumped over the lazy dog. I tried redownloading the technic launcher and deleted the files so i would have to redownload them and it did nothing.
I tested this in these mod packs:
FnD war pack & Voltz
