[Py2exe-users] Trouble building com server

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I was doing pretty well at building com servers for a while there, but
then I lost my mojo.

Bottom line:  If I use the com_server option in my setup.py, I seem to
build a dll just fine, but when I register by running regsvr32 on the
dll, a simple test script gives me a bizarre error.  But if I register
the classes with win32com.server.register.UseCommandLine, my simple test
script runs just fine.

The full details are included below.  Any help would be greatly
appreciated.  (Am I forgetting some crucial step?)

Thank you.
