First time using Movie Maker to make still photos from vacation into "movie".  It's nearly finished, including having added music.  I would like to edit a few things, but when I go back, now all I see is the same photo in every frame with no captions as were there before.  What do I need to do to see each photo (on the right) instead of same photo along with captions?
