?I have had mach3 on my office PC for many years with no problem. It is a i5 quad core 2.7Ghz 32 bit CPU running win7 ultimate. Today I wanted to run a G code program without a machine. Every time I clicked on the mach3mill icon the screen goes blank
and the PC reboots. All my other programs seem to work ok. The only thing I can think of is that thee were some recent win7 updates. Any suggestions?
