I have created a custom user control (completely owner drawn) that is contained within another user control (not-owner drawn, serves as a container) and whenever a form from another running application/process goes over the parent/container control, the graphics do not refresh properly.

UserControl Container (Non-Owner drawn)

--->User Control (100% Owner drawn)

(When another application goes over the surface of my user-control the owner drawn user control is in need of a refresh but it takes me minimizing the application to get it to redraw without any clipping.

Any ideas on how I might fix this?
