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

I actually have gone back to Limewire 4.18, it seems to run better

Thank you Paolo. That is what I did as well, when this first occurred. I am going to give the latest update one more chance. I am guessing it will probably do it again, and when it does, I will delete the latest version and go back to that last stable release series (4.x.x)
