Whenever I'm playing Super Smash Bros. a seemingly random issue with my keyboard seems to occur. The arrow keys only allow very small movements, not the full range as usual. And this happens seemingly at random, the game will work fine for a few weeks then just.. this happens. However oddly, when i load an older saved game file the controls work perfect on that file, however the current one never seems to work. Any ideas on how to fix this, i don't want to keep making new saved files to unlock all the characters to just have to this occur again. My settings for the keyboard where never touched and I've tried resetting them to defaults. Please help.
