Ever since I upgraded to 4.2.6, Limewire is extremely slow. I ctrl-alt-del and see that it's taking over 50% of "CPU Usage" Everything in the program happens at a delayed time, IE it takes a while for typing to show up in search boxes, and it takes a while for a dropdown to appear when I click "File" for example.

Anything in particular I should try?

PS. I've never had this problem before with 4.2.5
I'm running WinXP 3+GHz 512RAM
Shouldn't be a computer spec issue.
