Does anyone have the touch screen drivers for the MobileVu IV touch screen? It measures 12.1", it has the Northrop Grumman logo on the back, and the Part # is:46960-2. I've tried different types of drivers listed on the forum, but to no avail. Most of the software can't even find the serial port, but then some recognize the screen, but no touch screen feature. If there is software out there, what settings should I use when I install it? I'm using XP. Thanks!!!!
