title: DragMove() and Maximize
body: <p>I have a problem with my custom window (AllowTransparency, WindowStyle=None) in WPF. DragMove() method works good, but when I maximize window, or it maximizing automatically by Windows 7 Aero Snap, this method does not work at all. So I can't unsnap window with mouse drag and return it state to WindowState.Normal. Left and Right Aero Snap works good, I can snap and unsnap window without a problem. But when it maximized, nothing works except Win+Down  combination. Maybe somebody knows how to solve this problem or where can I find other ways to do proper DragMove of custom window with working Aero Snap features?</p>
