wine users - May 2003 - wine und MFC class CMonthCalCtrl

Hello list,
i use a new wine from may 2003 on SuSE8.0 and want to
run a self written Visual C++ Program with MFC.
There is a "CMonthCalCtrl" used, which displayes
a calendar und allowes to choose a day. This Control
doesn't work, the Selection by Mouse is not possible.
As i started it by "wine prog" in a shell, i can see
the wine output, but there isn't any warning or error.
What can i do to fix the Problem ?

THX
  Thomas
