Hanging code with axlSingleSelectPoint

Hi All,
First skill program...and it almost works.

Initiallly I wrote inline code that did not use a form but prompted the user to enter a point.  It worked, I did a calculation and the code exited cleanly.

Then I added a form (with buttons) but had a dummy callback and again forced the code to run once inline and it worked.

Now I have added a button callback which is working except for the fact that when the code is done executing the status light in the bottom right corner is green but says "Skill" whereas inline it would be "Idle" as expected.

By elimination I can get clean operation (but useless) by eliminating my call to axlSingleSelectPoint.  The code goes merrily on its way and alerts me that I failed to select a valid object and waits for a new button press.  All the while after each button press the indicator goes back to "Idle".

As soon as I re-enable the selectPoint call that piece of code grabs a point, determines what to do and executes with good results but the status is "Skill" at the end of the code execution.  It works repeatably for each button press.

So...what is it about axlSingleSelectPoint that might be causing a callback to hang?

Thanks,
Bill
