Limewire Pro closing/crashing
 

It seems to work fine while I'm at my PC, but if I go AFK for a lengthy amount of time, when I return LimeWire will have closed itself... or crashed. Technically I guess it's crashing, but I don't receive any kind of error message, so I say it's closing itself. Should this be happening?

What version of Java are you using? Try this version. Use the JRE offline installer & remove your current version of Java before you install the new one.
Java SE Downloads - Previous Release - JDK 5

I cleared the queue and it seems to be staying open. If it closes again I'll un/reinstall Java, the one you linked to. Thanks.
