I just bought two new touchscreens.

I have a GeForce 9500 dual video card on a Vista 64bit machine. The video is working but the touch ability of the second screen is not working properly.

Screen one works with the touch, but when I use the second it moves the cursor on the first screen. I have 2 USB cables hooked up but I think the computer only sees one.

It might help to know the type of touch screen. – MBraedley Aug 30 '10 at 17:28

From this article by one maker of touch-screens, Multiple Monitor Configurations :

Most of the touchscreens that we offer now support multiple monitor configurations in Windows (not supported in Mac OSX at this time). The touchscreen software driver will typically determine if a touchscreen can work in a multiple monitor system, as well as how many monitors are supported.

So it seems that it is a question of the video driver, whether it supports multiple touch-screens.
If that's the case, then the maximum you can do is update the video driver from the manufacturer's website, and hope.

Are both touch screens made by the same manufacturer ?
