This sounds like a common problem. I see five or so bugs with hang and focus in the title: http://bugs.winehq.org/show_bug.cgi?id=18371 http://bugs.winehq.org/show_bug.cgi?id=16136 http://bugs.winehq.org/show_bug.cgi?id=15485 http://bugs.winehq.org/show_bug.cgi?id=14456 Might depend on the window manager. Which desktop / WM are you using?
