I have come across a few potential bugs in the Reference Trace section.
1. On my Mac version, and I'm running the latest 7.05 too, the "Capture" button actually does the same thing as "Save". Or more correctly it seems to do a capture and save at the same time. Whereas if I press the "space bar" only a capture occurs (as expected).
2. Secondly, it seems that the stored date and time become the same for all measurements--it takes the date and time of the first input captured in a given session.
