What version of Java and LimeWire pro do you have?
I had a similar problem, and my thinker isn't working to good. I'm trying to remember what I did to correct this problem. I'm thinking it had to do with one of the power settings under the screen
saver or it went away when I upgraded my java or LW version.
I'm going to see if I can find that thread, because I asked about this same type of problem.
I found the thread.

The problem corrected itself when I upgrade LW.
