Crash when using RichEdit 2.0 and Composite Control

[atloc...@yahoo.com]

Hi, I'm trying to make a composite control that has a RichEdit 2.0
control in the dialog. When I add the RichEdit item from the toolbox
to my dialog and then run the control in the ActiveX Test container as
soon as the control starts to load I get a unhandled exception. This
occurs from a brand new ATL project with a brand new composite control
and seems to ONLY crash in the ActiveX Test Container (I.e. i have run
the control embedded in other software and it works fine).. Any help
with how I can get this working in the test container would be great!
Thanks!

Exception:
Unhandled exception at 0x1008f73d (Polygon.dll) in tstcon32.exe:
0xC0000005: Access violation reading location 0x00000001.

Just one more addition, I'm using Visual Studio .NET 2005, however i've
tried the same thing in 2003 and got pretty much the same result..
