Re: [CAD_CAM_EDM_DRO] Re: Windows Real-time

Whilew your at it, take a look at the different programs you have istalled
on the two machines. Software conflict is sometimes a problem. I ran into
this once with Microsfts Desktop publishing program. I installed it and it
"wiped out" my printer. Even uninstalling the program didn't help. I wound
up having to erase the hard drive completely and reinstall everything sans
the desktop publisher to get things back to normal!
