Hello
I thought this might be worthy if a new post so hear it is
After searching more I realized that Screens4 is not computable with Vista, but I keep playing with it and found if you just reduce your color depth from 32bit to 16bit it works fine, the easiest way to do this is goto your main vista screen and right click then select display settings and change the color setting on the right, worked great for me give it a try.
Thanks
