           Summary: System freeze/reboot required after switching from wine
                    to other apps
           Product: Wine
           Version: 1.1.2
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: john.moonsugar at gmail.com


So far this only happens when I play the game Morrowind.
(http://appdb.winehq.org/objectManager.php?sClass=version&iId=3383)
While in the game, running in full-screen, I use a window-manager（sawfish)
function to switch to a firefox browser window. At this point I often
experience difficulties in the browser within seconds to minutes of switching,
manifesting itself as losing the ability to do any mouse/keyboard input, as if
wine has stolen input focus without the game raising itself to the top. If I
switch back to the game at this point, everything is fine. I can switch back
again to the browser and continue to work, until the input problem happens
again. It's like something is reset by switching back to the game.

Now, if I leave the browser window on top, in the time it takes to go make a
cup of coffee my system will often enter into an abnormal state, the symptoms
of which are that when I try to do anything in the browser, it starts to work,
as evidenced sometimes by the little "wait" mouse pointer change, but then my
entire system locks up, I can't even log in from a remote system and I have to
reboot. There is nothing in my syslog.

The system freeze could well be a driver problem, I don't know how to find out.
I strongly suspect that the input problems are Wine though. And the 2 problems
seem related.

I feel pretty confident I can reproduce it at will, so if there's any more
debugging or instrumentation I can do on my part to shed light on the cause,
I'd be happy to try.

Here's some info about my system:
OS: Ubuntu 8.04
Wine: 1.1.2
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
RAM: 2GB
GPU: nVidia Corporation G71 [GeForce 7950 GT] (rev a1)
nVidia Driver: NVIDIA-Linux-x86_64-173.14.12 (very recent)
