I un-installed and re-installed everything and it looks to be a lot better now.
I will create a project and generate a tool path for it and cut the parts tomorrow.
I am just to tired to do it tonight.
But, from the small test I just did, I think you may have made the correct call to un and re-install all software.
Let me ask, is running on 64 bit a problem if just testing code using mach 3 as a simulator?
