I have been having an issue with Tracker regarding transforming between reference frames. In an activity, a student tracks the motion of two objects (A and B) and is asked to view the motion of B wrt A or vice versa. The coordinate system tracks along just fine but the data do not update for the change of reference frame.
I did not have this issue in previous installations, as the data seemed to update automatically (more or less). So, I'm wondering if this is a bug or if there is an extra step that I'm missing here. Would appreciate any help I can get here!

Hi Peter, thanks for reporting this. I can reproduce it so I must have introduced it in the last release :-( I'll make sure it is fixed in the next. In the meantime I think if you click on one of the track's steps to select it, the track data will update. Please let me know if this works for you. Doug
