After, I run MSWord 2007 (or Excel 2007) whether under wine or Crossover I lose all my applications top bars. That means I cannot maximize, minimize or move any of my applications windows. The problem can be cleared by a reboot, which is a pain. It can also be cleared with the compiz configuration settings manager. Under the general tab, deselect OpenGL, then re-select it and the top bars come back. That’s better but I finalyy got so annoyed I dropped back to an archived version of Office 2003.
