some of you might use Ultramon; it adds some very convenient features for the use of two or more monitors; unfortunately it's not that cheap. I just stumbled about this little freeware program called Oscar's Multi-Monitor Taskbar; it's not as powerful as Ultramon but has a couple of features as well, notably the Smart Taskbar which i find very useful.

What it does:
* It adds second taskbar to the extended desktop on Monitor 2 (either right or left)
* It can add third taskbar to the second Extended monitor if you have 3 monitors setup.
* It shows only applications from that Monitor
* It hides the applications on Monitor 2 from normal Windows Taskbar
* Adds a Move to Monitor button to all windows applications.
* Add Text Clipboard Extender (new 1.1.)
* Very carefully written, I don't want to crash my own desktop!
