Hi,
  If you run the Mach 3 demo (I am just trying it today) and hit the RETURN button, an input form opens and has the title "Preperation Positioning". It should say "Preparation Positioning". I figure it was something the developers were not aware of so I figured I would let them know about it. 
Grumple

The demo is the same as the full version, so the error is in both.
