> I'm sorry, but... What exactly should I do now to perform the test with a clean .wine directory? I don't really understand this very well. Should I try to install the software I'm running with each version of wine? How exactly? What exactly is a clean .wine directory? That would be perfect - but it is usually not required - try something like this: While in freshly compiled wine directory type in console: ./wine start /Unix /path/to/the/program/you/want/to/test.exe or WINEPREFIX=/path/to/prefix/you/use ./wine start /Unix /path/to/the/program/you/want/to/test.exe And look for the bug - then follow the guide at wiki.
