I was using version 1.9 beta and it didn't freeze, but it just dissappeared (mostly when I clicked outside the limewire window)
Since Limewire is the best program on mac for p2p downloads (according my humble opinion) I didn't remove it from my system and just reopened it after every crash, but I ended up regretting it big time...

I am using OS 9.2.1 and OS X (installed, but not using it ... yet)
