http://bugs.winehq.org/show_bug.cgi?id=4063 is a crash on exit from a VB6 app due to a _CheckNotSysLevel() error. What typically causes these - are they a bug in the windows program? And is there a good reference from understanding the whole syslevel thing in gdi? Thanks!

Does it help if you undefine STRETCH_VIA_DIB before MFDRV_StretchBlt in dlls/gdi/mfdrv/bitblt.c ?

The developers guide talks about this, because I once asked exactly the same questions :)
Syslevels are an internal mutex that understands ordering constraints, if a syslevel violation occurs it's always a bug in Wine and a backtrace can be useful to see how Wine got into the invalid state.
