--- Comment #2 from Lorenzo Ferrillo lorenzofer@live.it --- I can make obse work launching it with -nosync option (an optin that was intended probably to workaround a bug that existed in previous wine version, but it is no more an iusse with the recents wine development version and wine-stagingh until 1.9.8) Maybe a recent winestaging patch modified how thread synchronization work and it cause a deadlock in obse. I'm experimenting further.
However the bug can be workarounded.
