[THIN] Java dialog boxes

All,

Having an issue with a homegrown Java applet that keeps hanging Internet 
Explorer on our Citrix boxes.

Seems the Java applet is trying to popup a modal dialog box that somehow 
gets behind the IE window.  We got this from looking at the threads from a 
process dump of a hung IE instance.

The user can cause the hang pretty consistently by Alt-tabbing between 
seamless Citrix windows on her desktop quickly.

We're running Citrix 4.0/Windows 2003/IE6 on these servers.

Here's what we've tried so far...

Update the JRE configuration to disable DirectDraw support
Upgrade Citrix client to the latest version (version 11)
Disabled all IE Add-ons, except Java
Toggle the "Force offscreen compositing even under Terminal Server" 
setting in IE
Force the Citrix published application into windowed mode (TWIMode=off)
Cleaned out the published browser's cache
Upgraded Java on Citrix server (from 1.5.0_05 to 1.6.0_11)
Set the SeemlessFlags registry entry to 0x00027fb6

So far nothing has helped.

Anyone, have any other ideas?

Thanks,

Tony
