How can I display Execution Highlighting if it does not show up on my block diagram?

[Bigga]

I am using a baseline program provided with my zaber translational stage to write a more sophisticated program for the stage.  I have noticed that the execution highlighting icon is not in the block diagram.  I have been able to turn on the stop button which originally wasn't there during running, but I cannot find the option to turn on and off the execution highlighting icon.  Thanks for the help.

Most likely debugging is disabled in the VI execution properties.

Why do you need the stop button?

You betcha!  That did it.  Thanks a lot for the quick reply.  I use the stop button mostly for debugging in case I get stuck in an infinite loop.  Any suggestions for another course?
