conclusion is:
mouse work on patch1 and patch1 and 2 until you will not change focus to other window. When you will back to the application mouse doesnt work anymore.
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?
