Hey Hood, that works good here, neat trick.
(looks like a click anywhere in the window works while the requested line is highlighted)
Try this, while the code is running hit stop instead of Feed hold (I know you shouldnt....)or, EStop and rehome then enter a line # and do as you say above.
Notice after the prep move OK , the line # changes but becomes correct when you hit the start button the second time.
I think this is what Bob was seeing but nothing is really wrong, seems to run from the right line.
