Limewire4.12.3 Pro locks up
 

I've been using Limewire for years almost flawlessly except for one problem, if I click browse host on someone who shares more than 3,000 files it locks up about half way though. Only way out is to exit Limewire with task manager. No big deal except that it interrupts any downloads or uploads that might be going. I'm certain it's not my computer, tons of extra memory and other programs work fine while Limewire is frozen.

Is this a known problem that hopefully has been addressed with the newer version?

It could be a Java issue...
