--- Comment #10 from Ken Sharp imwellcushtymelike@gmail.com --- After the first BadWindow, "explorer.exe /desktop" is the process that disappears. Attempting to start it again has no effect and it silently exits. Any background apps running (Quicktime's tray exe for example) continue to run.
"wineboot -s" doesn't do anything either, neither does "wineboot -e".
