Vista Business Won't Retain Display Settings

OK....I have a SONY Vaio laptop running Vista Business. It has an NVidia
Geforce 7300 (I believe). I also have a dock for the laptop which I use
when I am in the office.

No matter how many times I set the display the way I want it (which is to
configure each screen independently...the laptop screen as well as the DELL
flat panel that I have connected via the dock......when I come back each day
and connect it to the dock, the video comes up ONLY on the laptop
screen....and it doesn't retain the display setting on the external screen.

Additionally, I have told Vista how to behave when the lid is closed
(selected "do nothing" on battery and in AC power) and that setting won't
get saved either. Sure enough, when I close the lid it triggers changes in
the settings when I have told it do nothing.

Does this have to do with the fact that I am using the NVidia graphics
adapter?

Any suggestions....it's EXTREMELY annoying.

Thanks.
