windows-7

Some portions of my application's interface are not getting refreshed after Windows 7 powers down the display. More specifically, I'm swapping out images, User Controls, and a button's content while the display is powered off and after it has been restarted, and this isn't being reflected in the UI until I minimize and restore the window or move it to one of the screen's edges.

I've tried calling the Window's InvalidateVisual() method when the app was in a state where it needed to redraw, and that didn't solve the problem. I have only been able to reproduce this issue on Windows 7. Any ideas?
