Java Applet Wont Load Past 80%

Someone is running a java based paint chat off of their home system, so far all of us have been able to load it all the way, except for one person who can't seem to get the applet to load past 80%.
She says she's got the latest update for OS X and she's gotten it to load before. She's tried updating Java and restarting her system. We don't think it's a firewall, seeing as other people can access it and she doesn't think she's running one.
Any thoughts on what the issue could be would be greatly appreciated.


Have her go to this Sun page and test her Java installation.
If there's no problem, she should look for a cause other than Java/applets.
If there is a problem, the page has troubleshooting information.
