the two screens are both your desktop. You configure in Control Panel | display the orientation (up/down, side to side). Your mouse then moves easily as if it were one screen.
So in my case, when I click the start menu and then move the mouse to the right, when it reaches the end of the first monitor, it moves to the second. I can then drag windows and things from one monitor to the other.
I set mine up with QA, Excel, mail messages on one window. Outlook, Word, EM on the other. After a few weeks I found which things I use together and separated these out. I can always move them, but they remember the last location. BTW, maximize only does to that window. Kind of nice.
