--- Comment #1 from Vincent Povirk madewokherd@gmail.com 2010-06-24 11:17:35 --- Could you get a +event,+gdiplus log and mark the point where you selected this option?
The +event channel will log a ButtonPress and a later ButtonRelease line for each click you make in a Wine window. Keyboard events are KeyPress/KeyRelease.
