WPF repaint issue

Question

I am having an issue with repaint of my WPF control.

The WPF control is added as an ElementHost.Child for a Windows form.

When Windows 7 goes into powersave mode and is brought back to normal (by moving the mouse or key press on keyboard), the rest of Windows form controls are repainted, however the WPF part is not repainted(and the Win 7 background is visible in that area).

On Minimize and maximise of the application, the WPF part is repainted.

Anyone has any idea about this problem?

The solution for this issue was provided in MSDN magazine a while back. It shows how you can make your WPF applications "power-aware" i.e. respond to power notifications. It's an amazing article and a "must-read".
