Hi Don.
I'm a long-time programmer with good (if rusty) knowledge of C/C++ and Unix, just getting up to speed on Linux. I'm at the point where I might be willing to tackle this myself, if the learning curve isn't too steep.
Great, that you want to help wine. Did you already got some guidance?
least, if there's a good way to get more information on the hangup, I'm definitely willing to add to the bug report.
Wine has support for a lot of Debug-Options:
WINEDEBUG="+relay,+seh" wine yourapp.exe 2>&1 >logfile.txt
Wine will log every API-Call and the Result for any DLL, that is present in wine (+relay) and every exception (+seh).
You can get a GB logfile very fast ....
