Recently for some reason, my limewire's been slowing down my WHOLE computer, I'll explain. Before i was using it and it was just fine, then one day it just started making the whole computer slow down, the animation of my mouse cursor glitches, things take long to open, and my music/sound is even slown down and glitching. this seems to happen now whenever i have limewire on, eventually the comp glitches up in a few hours of use. I'm not sure how else to explain it, but I've tried changing to the newer version and deleting all the old version files, but in vain. The problem has persisted, even when I uninstalled and reinstalled it, help would be very much appreciated, thank you.
