Hello All ! I installed XP pro SP3 on my "New to Me", "Digitizer" CF-18DDAZXMM. It came with no operating system and wiped hard drive. I work daily with a touchscreen CF-18 as part of a diagnostinc package and am familiar with its operation and functions. I am however a total "NOOB" at driver installation. After four hard drive wipes and as many driver reinstallations, I have learned to grind my teeth and swear simultaneously. I have read and reread the "CF-18 Drivers" thread(s) and become more confused the more I read. Should I be installing the Tablet version "Tablet Buttons Driver" or XP Pro version "Hotkey Plus Driver"? Tablet version"Touch Pad Driver" or XP Pro version "Touch Pad Driver/Touchscreen Driver"? What driver would be the "Digitizer" screen driverand how would the "Diditizer" screen be listed in the device manager? What driver would be the "Wacom" driver? The best results I have obtained so far have been all functions working except digitizer screen with correct stylus. At one point during my whirlwind of driver "Poke and Hope" installation,the curser would respond for a few moments just before the Windows Welcome screen fully loaded and would also respond just before the blank screen at shut down. I assume from this that the stylus and screen are hardware functional and that I have a driver or sorftware concern.Sorry for such a long post and so many questions! Any help with the digitizer vs touchscreen drivers would be greatly appreciated Thanks !
