Windows 7 - Dual monitors and photo screensaver

I have a dual monitor setup. In XP the photo screensaver would display pictures on both monitors, alternating between them.
On Windows 7, most of the image is on my left monitor (which is my secondary, extended display). Some of the image shows on the main (larger) monitor.
I would like the images to show on the big main monitor.

Anybody have any ideas?

See my post about using UltraMon 3.0.7 and Win 7 for a screensaver.

Looks like a very good app, however it's too expensive right now, maybe latter. I'm hoping that there is some setting that I have not discovered, or a registery tweak to make the screen saver run on the primary monitor.

I have this problem as well and haven't found a solution
