w this version, I cannot make it work. The only way to 'play' a segment seems to be to click on start time in the UL corner. Then hit play button/triangle. It starts at the start time, but continues past the end point/time in that segment. In frustration, I went to ?/help to see if you say how to use this interface. The videos there show the old interface, which indeed used to work. How do I get back to that interface? Or make this new one 'work'?
