Ahhhh! I have same problem with LimeWire after version 4.2.6 (it not hangs), verions starting with 4.3/4.4 hangs. Currently I trying to track down hangs...

I use operating system OS/2, and JVM ported from Sun JVM 1.4.1_07. May be nla1228 uses same version of Java? And same JVM problem exist in OS/2 and Windows? Simptom is absolutely same - table filling with search results and GUI hangs.

By tracking down this hang, I found that similar hang may happen when awt-thread and non-awt thread updating swing components at the same time.

May be in 4.3/4.4 some code which updates swing from threads executed without EventQueue.invoke(AndWait/Later) ?
