I've gotten this hang/freeze thing going on as well, and as with others, it was okay for a while, and then this started happening when no other changes had been made to the system, or the firewall. Uninstall/reinstall has been no help (not even the 'run once then crash' kind of help) installing the recommended Sun Java 1.4 (I had 1.3 before) had no effect, either. I can't figure anything out.

I'm using Windows 2000.
