I am fairly new, so I hope this isn't a dumb question. When I start my computer, and I click on the Mach 3 shortcut and when it opens up it seems to randomly open up two different versions. I have attached the different screen shots below. Any thoughts on how I got two different versions loaded on the computer, which one I should use, and what, if anything I should do with the other one.
Any Help would be great
