GetCurrentObject returns 0, but as far as it knows, it is
returning successfully.  This is because in the line

case OBJ_BITMAP: ret = dc->hBitmap; break;

dc->hBitmap is 0, although dc is a valid DC.  The HDC that is passed
to GetCurrentObject to get dc is obtained by calling
CWindow::BegingPaint(PAINTSTRUCT *) from a class derived from ATL's
CWindow.  I'm guessing that this is where the problem is probably
coming from - the app is written in C++ with ATL.


I've seen this occur when wine frees a gdi handle it shouldn't. Check
that the OBJ_BITMAP handle is really valid.

Also wierd stuff can occur if the app expects a HDIB but we provide it a
HBITMAP... or vice versa.
