[Wine] Application crashes when opening a graphics window under Wine

I am trying to run a Win32 application, Stable32, under wine.  This
application does analysis of numeric data files and can plot the data
to the screen.  When it does this, it opens a new window for the plot.

Under wine, the application starts just fine and the basic functions
seem to work, but every time I try to use one of the plot functions,
the application crashes.  This is the message it leaves behind:

wine: Unhandled page fault on read access to 0x00000000 at address
0x4c2543 (thread 0009), starting debugger...
Modules:
Cannot get info on module while no process is loaded
Threads:
process  tid      prio (all id:s are in hex)
0000000a
        0000000c    0
        0000000b    0
00000008 (D) (null)
        00000009    0

I've done some googling, and I find several mentions of "unhandled
page fault on read access" to various addresses, but not much that
would lead me to a solution.

Two points that might or might not be of help:

1.  I ran an earlier version of the program under an earlier version
of wine without this problem.

2.  The DLL files that the application uses are a mix of upper and
lower case.  Is wine case sensitive when loading DLLs?

3.  The application seems to open in separate windows under wine.
When running under Windows, it uses the more typical single window
with subwindows inside.  Might it be possible to tell wine to open the
application in a "single window" model?

Thanks for any tips on how to resolve this.

Thanks,

John
