Well Ben, whatever you did worked.  I haven't had the error since putting those assemblies on my machine.  I have gone into the mapper changed some customizations and built some partials all without error.  And the form actually comes up normally, no more transparencies where the paint didn't work.   THANKS!!!

Excellent   The good thing about OnPaint is that you can try/catch it and if it fails, the WM_PAINT message is sent so much that it will just paint again (likely succeeding the second time).
