What is "Make Primary" supposed to do?

[Nick Mirro]

It doesn't seem to do anything. I'm using 2 cards and latest
Catalyst.

HD 3800 (2X DVI + svideo) 1. Samsung 1600X1200
HD 2400 pro (DVI/VGA = svideo) 2. Samsung 1280X1024

These displays are extended.

I was hoping to have the Start button, taskbar, etc. switch to the 2nd
monitor when I make click "Make Primary". Nothing happens. Even with
2 video cards, can I not somehow alternate which shows the Windows
"Start" button?

Are you clicking the "Apply" button as well?

Thanks for helping with this.

When "Make Primary" is clicked, the display adapters reset, causing
the "keep changes" dialog to appear. This applies the setting so that
"apply" is not an option after the change.

I did notice that my autohide toolbars switched to the newly selected
"primary." Also, apps open there as well. Only the taskbar remains
in the old location. Is there a taskbar setting or something that
might be causing this?
