I sometimes getting projects which, seem to freeze, even the preview thumbnails don’t animate......or they just go on forever without completing........
May have found a solution......I removed all the titles except one, then added them ALL again then removed the old previous one.....
Did this twice now and seems to work perfectly.....maybe there is a glitch sometimes when the video titles are read in, but without reporting an error...
Thought it was worth mentioning, as could help,others
