I am seeing a behavior which I don't know is intentional or a bug. When I maximize any window in Window 7, the border clips. This is becoming an issue for the application I am designing in WPF. It has curved borders, and the visual appeal changes because of the clipping of the borders. Here I give you an example from Visual studio. Normal window: http://drop.io/rtg2tvg/asset/windownormalstate-noclipping-png (See the curved border) Maximized Window: http://drop.io/rtg2tvg/asset/windowmaximizedstate-clipping-png (Maximized state, curved borders are clipped) Thanks for the reply.

Hi ulahoti, I think this is by design. When maximum a window, the window will be expanded to fill the desktop.

If this is by design then it is a bug. The Windows shouldn't be clipped when it is maximized. I am creating a custom window with following settings in WPF: WindowStyle="None" ResizeMode="CanResizeWithGrip" AllowsTransparency="True" So I don't have a default border around the window. Is there a way to prevent the clipping of few pixels?

Any comments please. Is this a fixed expected behavior or a configurable behavior. If anybody from MSFT can comment I will appreciate greatly.

Any comments please. Is this a fixed expected behavior or a configurable behavior. If anybody from MSFT can comment I will appreciate greatly. Hi I'm fairly sure this is the expected behavior in windows. If you look at any window that is not maximized you will see that they all have rounded corners. I would recommend that you post this question on the WPF forum. Windows Presentation Foundation (WPF) Forum Someone on that forum may have more definitive information. Let us know what you find. Thank You for using Windows 7 Ronnie Vernon MVP
