Adjust Window Mode Settings
You can customize how Parallels Desktop appears and behaves when in Window mode.
Set Whether Windows Programs Show in the Dock:
You can choose whether or not to show icons for Windows programs in the Mac OS X Dock when in Window mode. If you prefer to work with programs by manipulating them on the Windows desktop, you may not want to be distracted by seeing them in the Dock alongside your Mac OS X application icons.
Set Whether Animations are Used for Some Actions
By default when you pause, suspend, or shut down Windows, the Parallels Desktop window becomes animated. If you find this distracting, you can turn off the animations.
