UK Bob,
I'm pretty sure I have enough computer for the job not that it's a monster. 1.33Ghz Athlon, 512Meg RAM.

I don't think LimeWire should keep the computer locked up for five to ten minutes at a time before I can get a response from it. Should I see if the development guys are interested enough to have me do some sort of monitoring?

stief,
This is consistent. Fire up LimeWire and the system runs out of gas every time.
