9800gtx nvidia vid card and dual monitor help?

ok, so recently upgraded mobo/proc/ram, kept the same video card. before the switch i had dual monitors set up, with the larger one on the left hand side and display 1 (main display) with smaller on right side and as secondary. with this setup, if i wanted to drag open windows to the other monitors (say from the main left monitor to the secondary right monitor) all i would do is drag the program from the left to the right. now after the upgrade (and downloading the newest drivers for win 7) the physical locations of the monitors are the same, the larger monitor on the left is still the main display (1) and the smaller on right, but when i want to drag items from one screen to the next, i have to drag the opposite way of the monitor i want it on (ie drag open program from left display to the right, i have to actually move the cursor to the left before it shows on the right monitor). i have no idea whats different, ive tried changing the main display back and forth, ive tried swapping the physical plugs on the video card (where they plug in) ut no matter i have to move the cursor the opposite way i want it to go, how can i get it back to how i had it??|||Right click on your desktop, select properties, then settings, then drag the monitors around to the way you want them.

Hope this helps, I f you need screen shots, etc, just ask. Daniel.
