Java applet enabled site crashes in citrix

We have our ERP application uses Oracle Java initiator ver. 1.3.1 xx. When users access the webpage with Java applet enabled, the browser crashes without giving any clue. The browser disappears. Here is the environment:
Windows 2003 64 Bit, Presentation server 4.5, IE 6 and Firfox browsers.

Can any expert give a hint how to solve this?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If this is just recently, my company has experience something similar.  I am thinking at this point it was a recent Windows Update.  I have nothing specific for you.  On most systems removing ALL Java clients including the J-Initiator then rebooting and re-installing the J-Initiator has fixed our issues.

Hope this helps!.....:)
