multiple-monitors

I have a USB-to-VGA adapter, which I use to connect a second monitor to my laptop (totaling 3 screens). It worked alright with Vista.

I upgraded to Windows 7, and now it no longer works properly (I downloaded the latest drivers just to get it to work on 7). The extra monitor is detected and used to extend the desktop (I can move things onto it, etc), but is not shown within the Control Panel. This is annoying because now I can't changes its resolution, set its logical position to match its physical position, etc.

Can I do anything, besides waiting for better drivers? I'm mainly concerned with moving its logical position. (I'd also like to understand how Windows can use a monitor it can't detect. Weird.)
