Issue with DeckTools app in Windows. The problem is that Application window (work pane) flickering (it becomes black) after uypgrade to Parallels Desktop 10. This app worked properly in Windows even on Parallels Desktop 7. My Host OS X is 10.7.x
In Parallels Desktop 10 we have improved OpenGL support for OS X 10.8.x that might cause some troubles on OS X 10.7.x.
The only possible workaround for this particular case is to downgrade to Parallels Desktop 9.
