Summary: Moving child window hangs X with flashing cursor
           Product: Wine
           Version: 0.9.61.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Poser 7.0 is a 3D model manipulation and rendering program.  It has a main
background window and several child windows, including a 3D viewport using
openGL.

When running on the KDE desktop using the Window Manager, moving the window
causes the cursor to flash between the normal pointer and the cross shaped move
window icon, and the mouse buttons and keyboard to become unresponsive for
between 20 seconds and one hour. Eventually the flashing stops and the window
can then be moved.

When run on the desktop without using the window manager or decorations, this
problem does not occur.  However, when the 3D window is manipulated, the child
windows all disappear behind the main window (bug # 13065)

I'm running openSUSE 10.3 with KDE 3.59 and the nVidia proprietary video
drivers.
