Summary: X11 refresh does not work
           Product: Wine
           Version: unspecified
          Platform: PC
               URL: http://download.utorrent.com/1.6.1/uTorrent-1.6.1-
                    install.exe
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When uTorrent starts, it works fine until the user changes the desktop. When the
user returns to the original desktop, the uTorrent is blank/black.

How to reproduce this bug ?
- download uTorrent from here
http://download.utorrent.com/1.6.1/uTorrent-1.6.1-install.exe
- install it
- start the uTorrent
- start downloding 'something'
- switch the Destop
- return to the original Desktop (the one where you've started uTorrent)

ACTUAL RESULT: uTorent is blank
DESIRED RESULT: uTorrent should have all the buttons/panels/etc visible

ADITIONAL INFO:
uTorrent does NOT die. It continues working. Files still get downloaded... but
there is nothing user can observe, modify, stop or start... because the uTorrent
window is blank
