I''m trying to create a D3D window with a spinning triangle. I want the triangle to spin even when the window loses focus. Unfortunately, if another window completely covers the D3D window, the mouse movement is choppy and the mouse freezes every second or so. If a window partially covers the D3D window, everything is ok. I''ve searched for an appropriate windows message but I''ve been unable to find anything. I''ve sure someone else has seen this before. Can anyone help? Thanks.
