Hello. I'm trying to use my old Mach 3 xml file on a newer Win7 computer with SP1. I"m using the same LPT printer card/cable which worked before. My Mach 3 and Gecko 540 setup is working as recommended. But when I connect the LPT cable nothing works as it should. I sometimes get a BSOD when I close mach 3. I also get a BSOD when I try to use the Utility for checking the OS frequency. Are there some specific MS run-times I might need? I'm wondering if my LPT pci card might be bad.
