After upgrading a project from SF v1.5x to v1.6 I’m having problems with the Infragistics controls. I have Net Advantage 2006 vol 3 installed on the system and have added the references to the updated DLLs to the project reference list. Everything compiles OK but I’m getting an error when I try to access a Infragistics control. If I delete then re-add the control it works okay.

Yes, and no, Larry... when I drop a wrapped UltraComboEditor on a form and set the sort, then yes, it throws the exception... however the stack trace does not reference a single StrataFrame method.  So, I wanted to debug the issue and see what was being set to null, so I opened up the Infragistics source code, but since they do not distribute the .snk file for their source code, I had to change the reference to my compiled DLL.  When I did that, everything worked perfectly... no issues.  The only thing I did was change the reference.  It was the exact same code (at least I think it was... the source code they distribute might be different from the source code used to build their deployment DLLs).  So, I don't know what to tell you.  Yes, I can reproduce it, but looking at their code I cannot even fathom what might be throwing a NullReferenceException (all it does is retrieve a bunch of appearance stuff).  And when I build their source so that I can step through it, everything works fine, no NullReferences.
