CrossAppDomainMarshaledException in V1.1 DeepEarthPrototype

Jan 31, 2009 at 11:00 PM
I'm getting a CrossAppDomainMarshaledException exception in v1.1 of DeepEarthPrototype that crashes the browser.  Version 1 of the DeepEarthPrototype works just fine for me, also v1.1 of VEDeepEarthExample works just fine.  Any ideas as what changes between v1.0 and v1.1 may have caused this.  Unfortunately there is nothing on the callstack that sheds any clues.  I'm not familiar with this codebase - just started to look at it this afternoon, when I debugged it, all the methods in the Page ctor are executed without error, I see the black background of the control and the tool controls are visible then the exception occurs, and the browser crashes.
System.CrossAppDomainMarshaledException was unhandled
