Thanks. To the best of my knowledge I have never intentionally used Full Duration.
What I'm doing here is adding a few slides of intro to several existing presentations. I made a small project to create and debug the intro. And now I'm copying a small number of slides from that project, including a couple blank slides, to the beginning of some of my slide shows. The blanks didn't seem to copy well, but now I think I have the right process worked out.
I'm a firm believer in "just in time learning." This was the sort of situation when I really wished software makers would still provide manuals that were indexed' so that one could find and correct these little gotchas. I guess I'm too old-school. I watched all of Barry Beckham's videos a while ago, but I can't retain everything. And it's nearly impossible to find the right video.
Thanks for your help.
