I concur. Purchased new computer to operate as controller; came loaded with Windows Vista Basic, everything boots up & works fine, but whenever I close Mach 3 or the driver test routine everything ( mouse and keyboard) quit responding. Set the system up for dual boot with XP as the second OS - same problem under XP. Tried removing that hard drive & installed another with XP only on it - still the same problem. Added RAM to a total of 1Gb - same problem (but I can get there faster). I have 2 other computers (XP OS) which work without problem, however I need these for other applications. I can't find any differences in the LPT1 settings. Haven't found the error logs yet & I'm a bit hesitant to dive into the registry for answers.
Any thoughts anybody?
