>Hi All,

>You know there is a setting in Windows display options called "Show window contents while dragging" - this shows the window's contents when you move or resize the window, dynamically resizing the contents if necessary. Is there a way to switch that off from VFP or, at least, tell my VFP app to ignore that setting. When this setting is off only the border of the window is moved or resized and once the operation is complete only then does the window contents refresh.

You can set .Dockable to 1 instead of the default 0 (2 doesn't do what you want). However, border redraw performance on Vista and Win7 with Aero enabled is abysmal and sometimes leaves trailing screen artifacts on my system (Win7). Win8/Server 2012 don't have Aero, maybe that won't be a problem for you.
