I'm trying to make dialog boxes run alongside the main window with DirectX still rendering to it, so that the updates from the dialog box can affect what's being rendered. So I make the dialog box run modelss by using Show() and everything works fine except for one small problem. When I drag the dialog box anywhere, while it's being dragged, the main rendering window freezes with no updates, and I'm left with an ugly grey streak across the screen until I stop dragging the dialog box. Is there any way to fix this?

Override the Move event of the dialog and call the Update method of the parent.

ahhhh thank you [smile]
