           Summary: BPM Studio crashes when playing a sound
           Product: Wine
           Version: 1.1.6
          Platform: Other
               URL: http://www.bpmstudio.com/
        OS/Version: other
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: directx-dsound

I looked into this app because it was mentioned today in:
http://www.linuxquestions.org/questions/linux-software-2/what-programs-would-you-like-to-see-ported-to-linux-105955/page228.html

It installed fine, although it couldn't install its kernel driver:
fixme:setupapi:SetupDiGetINFClassA "C:\\Program Files\\AlcaTech\\BPM-Studio
Demo\\\\Drivers\\Kernel\\mmrtkrnl.inf" 0x7d9688b8 0x7d968898 32 (nil)

The app also seems to run ok.  The main hitch seems to be a dialog
that comes up on first run saying "Searching..." which takes forever;
fortunately, you can cancel that.

The first thing I tried to do was play a .wav file.  That crashed
with an uninformative backtrace. Happily, turning on +relay,+seh
caused it to magically give a much more readable backtrace:

0030:Call user32.GetCapture() ret=041b77d8
0035:Ret  KERNEL32.UnhandledExceptionFilter() retval=00000000 ret=7efc66ea

0030:Call user32.WindowFromPoint(000001b8,000000ca) ret=041b4a14
Unhandled exception: divide by zero in 32-bit code (0x7dbf7f33).
Backtrace:

I'll attach the .wav file in question, just in case.  I doubt it matters much.
