JRE running inside custom browser (win32 - iwebbrowser2)

Question

Hello,
I have created a browser using the IE browser control (iwebbrowser2) and its having some issues when trying to execute applets. When my browser encounters an applet on a web page - It does not load the Sun JRE which is set as the default in the IE options. IE on the same computer, however, does load the Sun JRE. The iwebbrowser2 hosted app first attempts to try to load the SUN JRE, then the Sun JRE appears to fail, and then the MS JVM loads (if it is installed on the computer).
Making matters worse, if no MS JVM is installed, and the Sun JRE in the custom browser does load the Sun JRE, but some applets just hang. The same applets do not hang in IE with the Sun JRE.
Is there something that needs to be done to tell the custom browser to load the Sun JRE? It looks like the Sun JRE fails after a call to:
DllGetClassObject which is called from "SSV.DLL".
Looking at the results of DLL loads with a debugger, IE seems to load and map SSV.DLL early on in its startup phase.
Even more freakish. If I rename my browser to IExplore.exe - then the Sun JRE does become the JRE thats loaded. Of course, this is a bad solution and the same applets lockup, so certainly there is something more to do.
Anybody have any idea about how to deal with this?
Thanks!

Here is the example from the Acrobat JavaScript Reference API: 
Detect whether this document is in a browser or not.
if ( this.external )
// Viewing from a browser
else
// Viewing in the Acrobat application.
