Why is the Table Display (little black screen with red toolpaths) working on my Comprehensive Run Page, but NOT working on my Simple Run page?
On the Comp Run page, it's showing all movements, and toolpaths.
When I switch to Simple Run page, the screen is just black with the pink/purple crosshairs doing nothing.

Have you tried the "Regenerate Toolpath" button?

Click regenerate toolpath button located below and left side of the screen.

Mine does this quite often.

I tried the 'Regenerate Toolpath' button during the program run, and nothing happened.
HOWEVER.....
When the program finished, and reset (M30), I tried 'Regenerate Toolpath' again, and VIOLA! it worked!
I guess the program needs to be reset and waiting when the button is pressed.

More often than not when I load a program the table display window you are speaking of does not display the tool paths when the file is first loaded so I always hit the Regenerate Toolpath button before machining just as a matter of routine.
