In the latest project I'm finding that when I double click on a clip to select it the preview window is displaying a picture of the last frame of the previous event. Double click on the 5th clip only to see in the preview window a still of the last frame from the 4th event, etc & the same thing happens all of the way across the timeline as I click each event. If I click play the clip displays correctly. Is this a bug or is this related to wrong settings?
