Hi Jason,

 I overlooked something you mentioned. Sorry. It is true that if you begin to 
measure the angular distance on a star, and the transient label pops up it 
does not disappear until you finish the measurement. Further, the right 
status bar does not get refreshed with new coordinates while moving the 
mouse. But the angular distance measurement is correct. 

I will have a look at the code to understand what is going on. I will have no 
time for that may be till the weekend.

regards,

Pablo.
