Hi, I am using the Limewire 4.911 Beta, while 4.8 seemed to work great. 4.911 is maxing out my cpu.

Limewire 4.911
Windows XP Home Edition
Amd Sempron 3000+, 2.0ghz
1 Gig of Ram.

I'm showing 2 seperate instances of Java installed in the Control Panel.

J2Re SE v.1.4.2_07

and

J2SE Runtime Enviroment 5.0 Update 2

Limewire itself is only using ~15% of the CPU power, but SYSTEM ends up using the the remaining CPU power. This causes Limewire to lock up for a few seconds at a time, especially when downloading more than 10 files at once.
