I have a Lenovo T400 laptop with an ATI Mobility Radeon HD 3400 Series video card, using the ATI Catalyst Control Center to span my Windows XP display over the laptop display and a Dell flatpanel LCD.

This works fine, but I'm used to NVIDIA multi-desktop that let me control the "Start bar" to either exist on only 1 screen... be duplicated on both, or (what I want), stretched across both.

Is this possible with the ATI card/Catalyst Software? If not, are there any utilities out there that will handle this for me?

That is, what I have:

+----------+      +----------+
|          |      |          |
|  Lenovo  |      |   Dell   |
| (primary)|      |          |
+----------+      |          |
|Start Tray|      |          |
+----------+      +----------+

And this is what I want:

+----------+      +----------+
|          |      |          |
|  Lenovo  |      |   Dell   |
| (primary)|      |          |
+----------+      +----------+
|Start     |      |      Tray|
+----------+      +----------+
