dual-monitor

I recently updated my nvidia driver... now I have to re-establish the connection to my second monitor everytime the laptop goes to sleep. When I open the NVIDIA control panel, the second monitor is listed there but the checkbox beside it has been cleared. Oddly my laptop screen is identified as display #3 and the external screen as display #4.

Is there a registry key that I can clear to get them set back to #1 & #2? Will that fix the problem? Or is there a simpler solution.

(It's a Dell Studio XPS laptop with GeForce 9500M running Windows Vista 64-bit)

TIA
