[2005] Simple WebBrowser runs on XP not on Vista (1 line of code)

Hey Guys,

For the life of me I cannot figure this out. I've added a WebBrowser control and one line of code:

In the Form_Load event:

Code:

---

wb.navigate("http://superpass.real.com/bbchat")

---

When developing the application an XP machine and running this application on XP the application loads fine. When running it on VISTA the application crashes with a "not responding" error.
When developing this application on a VISTA machine and running this application on XP the application loads fine. When running it on VISTA the application loads fine as well.

The problem is that I need this to work on an XP development machine and then run on Vista without crashing.

Any ideas why it works on a Vista development machine but the same code won't on an XP development machine and run on Vista?

If it helps, the page simply loads a JAVA Applet. That's all there is in the HTML. It's a chat application from prospero.com
