--- Comment #10 from patryk@kowalczyk.ws ---
Ok , thanks, so either the stub is insufficient, or it might be another problem. I guess I the bug remains open then; Last question: does emulating a virtual desktop (in winecfg -->graphics) change anything?
Hi, Yes, emulating a virtual desktop "solved" the problem and mouse working when you change focus to the other window.
best regards,
