D3: MDI Children in a DLL?

Hi,

Has anyone been successful in putting an MDI Child form into a DLL and then
merging it in with an MDI Parent form in the main EXE?

I've had no problems getting a Non-MDI form to appear as part of the main
EXE, both in Modal and Non-Modal fashions.  When attempting to do the same
with an MDI child I get an EInvalidOperation in the DLL or (if done as in
In-Process COM DLL) 'Cannot create form.  No MDI forms are currently
active.'

I would most appreciate any suggestions you have!

Thanks,

Adam Purcell
