xp sp3 Toshiba Tecra ie8 upgrade from ie6 has made my dual display setup a bit odd. Dual display setup is a bit weird to start with, being under control of ATI Catalyst, but was okay with desktop background image fit to each screen. After ie8 install, xp has decided to "tile" the 2 images. ending the left one on the notebook lcd about 1/4 inch before the actual right side of the screen. I don't know any of this has to do with ie8, but that is when it went a bit odd. How can I check that my screen resolutions and desktop size still make sense - that ie8 hasn't screwed something around on me? I think I remember sometime in the past telling Windows that I want a desktop that is spread across the 2 screens, but now I can't find where that might be.
