>From what i've seen the windowproc pointer points to possible heap area
(0x7d28dc7b) which seems invalid - hence the access violation.
I remember some rare occurrences where WindowProc() might get called with
dangling pointer.
For instance when bugged code uses class libraries (like ATL, MFC and the like)
incorrectly by deleting window objects (like CWnd...) before calling
DestroyWindow().
There are cases where even class libraries contain such bugs (like the dreaded
"delete this" in OnFinalMessage() )

I would test this app using native windows. Wine isnt useful in this case.

Please run the software using "Windows Application Verifier"
(http://www.microsoft.com/technet/prodtechnol/windows/appcompatibility/appverifier.mspx)
 tool.
Here is a little "howto": http://msdn2.microsoft.com/en-us/library/ms807121.aspx

If the software is bugged, the tool should report heap issues ("Page Heap")
prior to crash.

Report back if you encounter any problems or have new info.
