Can u tell us more about your computer??
What O/S are you using?
What version of limewire?
Does this problem only happen when you use limewire? or are other programs affected too?
Did you recently install or upgrade a display driver or anything else?
Did you try uninstalling and reinstalling limewire?
And anything else you can think of that might help identify the problem, no matter how small the change.
THANKS:)
