--- Comment #19 from Alexandre Julliard julliard@winehq.com 2007-09-01 03:37:14 --- The tool windows really should be managed, that's not going to change. And yes, that fixes the bug because the resize is now done by the window manager instead of being done internally in Wine.
The problem with resizing inside Wine is that we need to grab the X server, and depending on what the app does during the resize this is quite likely to deadlock. Wine has no business resizing top level X windows, that's the job of the window manager.
