I CUT THE FRAME DURATION DOWN TO 2.5 SECONDS TO FACILITATE INCLUDING IT IN AN E-MAIL. THEN SAVED IT. AFTER THAT WAS DONE I INTENDED TO CHANGE THE FRAME DURATION BACK TO 7 SECONDS. I OPENED THE FILE UP IN MOVIE MAKER LIVE TO DO THIS AND DISCOVERED THAT THE DURATION TOOL WAS INACTIVE NOW. WHY?? I LOADED SOME OTHER PHOTOS AND IT WORKED FINE.
