Have it working fine under Windows 2000, but NOT yet on XP Professional. Does anyone know which interface works under XP. Tried the compatibility boxes, did not work, have a 32-bit card but the VXD did not work and get me to the calibrate I found under Windows 2000. Putting it on another machine running XP. Anyone got it up and running on XP, and if so, how did you do it? Got a Dell Precision 650 workstation running XP on the other computer. Windows 2000 working fine, but not the XP yet. Thanks for any suggestions.
