[Tom Goddard]

The user entered a non-numeric value in the Segger maximum number of regions GUI entry field. Would be nice if Segger gave a more friendly error when an entry field has an invalid value. I've seen other bad entry values in other fields produce tracebacks but only a few times. Since it is rare and a lot of code needs to do checks to catch these problems, and we did not develop Segger, I don't plan to add all the error handling.
