Actually, I am still experiencing the same problem. I highlight the code I
want to step through and click the step button to bring up the step window.

It is stating all "All of the definitions have been successfully evaluated."
And then no stepping can be done and the above error still occurs.

The only way I have been able to get the stepper to work is to write code
errors purposefullly, this allows me to circumnavigate the  "All of the
definitions have been successfully evaluated." statement and allows the
stepper to function.
