I have a need to be able to run several (three) different apps at the same time for what I do. When I launch Limewire, and begin anything, searching, downloading, etc. my cpu hits 99% and everything else freezes. Limewire 5.0 had all the cpu cycles.

OS XP Home, SP 2 installed
Cpu AMD Athlon 2.19G 3200+
1.5G Ram
