Help me run a touch screen monitor along with a non touchscreen monitor

I need to be able to run a touch screen monitor and a regular monitor on my Windows PC at the same time. The display must be extended across both screens. My video card has two outputs so no splitter is used. My problem right now is, when I have my touch screen and my non touch screen connected to my PC at the same time, any time I touch the touch screen, the mouse moves on my non touchscreen monitor, instead of on the touch screen. ? If I go into my display settings and only display my touch screen, it works fine. The issue is only when both touch screen and non touch screen is used together. My touch screen is connected via DVI cable and also via USB to control the touch input on the screen. This will need to work with Windows XP and Windows 7. The touch monitor that I am running is the ELO ET1545L. ## Deliverables I need to be able to use a touch screen and non touch screen monitor attached to my PC at the same time. The mouse needs to be able to make selections on both monitors. If the mouse is located on the non touch screen monitor and the user presses the touch screen, the input must register on the touch screen, not the non touch screen monitor.
