We need to know what the app was doing right before the
crash.  Often running with
  WINEDEBUG=+relay wine stable32.exe > log.txt 2>&1
will get us the info we need.  log.txt is often quite large
so it's best to compress it with e.g. bzip2 before sending
it.  And it's best to *not* send that to the newsgroup;
rather, send it straight to an interested developer (like me)
or file it as an attachment to a bug report at bugs.winehq.org.

Which version?  It helps to know what was the latest
version that actually worked.
(BTW the vendor's web site even mentions Wine:
but the info there looks about four years old. )

Nope.   MiXeD case is fine.

I'm not familiar with how that works, so I don't know.
