MAPI Forms are not displayed in OL2003

[Uwe Kurze]

hi there,

i have developed an outlook form in c++ and it works fine in all
outlook versions. but now with OL2003 my form crashes when i try to access
the lpMessageSite pointer or lpMessage pointer (i retrieved via
IPersistMessage::Load):
i.g.
hRes = m_lpMessageSite->GetSession(&m_lpSession);

there is no c++ exception to catch.

(the lpMessageSite, lpMessage seems to be valid pointers)

i tried other sample code with the same result.
it seems there is no running c++ version for a form under OL2003.

any ideas or same problems or other expirience

thanks uwe
