--- Comment #7 from Rico kgbricola@web.de 2013-04-22 03:05:22 CDT --- Well, have a look at the wine version, which crossover uses (wine-1.5.15?) and try plain wine with the same version.
Now you should be able to see, 1. if it is a regression in wine (does the old - same as crossover uses - wine version work?) 2. if it might be a configuration issue in wine (you may run with normal wine in the crossover prefix - save your data first!) 3. if some patches in crossover make it work or there may be a workaround in the fglrx driver which gets triggered by crossover but not by wine ...
