Powerpoint acting strangely with PrintWindow

[Rick]

Hello,

I'm writing an app that uses the GDI PrintWindow routine to capture a
snapshot of a window. The problem is that some window with an image redraw
that image covering the client area. Powerpoint is one such window. Anytime
I try to capture it, all images on the page are redrawn up and to the left,
creating double images.

Does anyone have any experience with this? I need a clue.

Thanks,

Rick
