Hi Emanuele, After poking around a bit, there seems to be a logical problem in Wine's GDI code. From the backtrace, SelectObject on this object calls BRUSH_SelectObject, which uses a bitmap and eventually GetDIBits, which tries to CreateCompatibleDC (or sometimes DeleteDC instead). However, SelectObject always calls GDI_GetObjPtr, which calls _EnterSysLevel and not _LeaveSysLevel. But the CreateCompatibleDC complains and dies if you have had an _EnterSysLevel and not a _LeaveSysLevel.
It might be that BRUSH_SelectObject really should use a different set of "internal" functions that won't complain about locking. Or maybe DeleteDC and CreateCompatibleDC should just increment the recursion level instead of erroring out. I don't know, so I'm forwarding to wine-devel for greater insight. - Walter Here's a summary of the relevant part of my backtrace again: 1 _CheckNotSysLevel (complains!) 2 GDI_CheckNotLock 3 DeleteDC 4 GetDIBits 5 MFDRV_CreateBrushIndirect 6 MFDRV_SelectBrush 7 BRUSH_SelectObject 8 SelectObject - calls GDI_GetObjPtr, which does _EnterSysLevel.
