Since upgrading to Windows 7 from WinXP, my dual monitor causes issues with my icons. I have a laptop as the primary (1280x800) and a flatpanel as the secondary (1280x1024). In the Setup, they are configured to be offset from one another so that the bottom of the flatpanel is higher than the bottom of the laptop (which means the top is much higher, given the sizes). The Laptop is the left monitor, and the flatpanel is on the right.
When I'm mousing around on the laptop, and go against the top-most edge, the icons start sliding down! Since the screen is full of icons, the lower-most icons completely disappear off the bottom of the screen. They seems to slide until my mouse has moved to the "logical" location of the other monitor, then they stop.
If I click any single icon and drag it to a new location, all the icons snap back to their original locations.
What is going on here!
