I had to upgrade my Java Runtime Environment when I upgraded my LimeWire last night. my screen now freezes for shor periods of time and when I click on the start button, the start menu flashes adn my cursor constantly flashes. Not sure how to fix this. I also get an error communication box that says "unable to write a necessary file because you do not have permission, your settings will not be saved for your next use of LimeWire". I need some direction. Thanks!
