When using LimeWire the only progs are the background apps and I concentrate on LimeWire. Approximately 50% of my HDD is empty, I have a P4 @1.8 MHz with 2 Ghz RAM. WIN XP SP2 installed and using Roadrunner Broadband. Now I share only about 260 files and run like a top except for the glitches in LimeWire. I tried sharing approximately 8,000 various files but now settle for these PRIME files.
