Windows Photo Gallery:  When I downloaded this program and began a slideshow the videos showed automatically in the right place.  The Slideshow icon on the tool bar had a pull down with the themes.  And, when the slide show started the advance, go back and pause commands were on the right, left and bottom, not all on a silver bar at the bottom of the screen along with small theme and settings marks.  Now the pull down theme command is gone from the slideshow icon, the slideshow skips the videos and when the slideshow starts it has the the silver command bar at the bottom.  Thanks for any help.
