Comment 31 for bug 940603

I have hit this bug a few times on my machine, when I type "xlsclients -al" I see the following in addition to what I had running before the white box appeared on the screen:

Window 0x3e00001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe
Window 0x4000001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe
Window 0x4200001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe

Tried to xkill by id, but the window still persists.
