Yes, the names are identical. I'm afraid I don't understand your instructions, Bob. You want me to paste an MSO from one layout to another, rename it, then rename it again?

I have tried simply copying and pasting an MSO from one layout to another, and ensuring they have the same name (by deleting the space+'2' in the pasted copy). It does not work: MSOs reset themselves when you rotate the iPad.

Is this perhaps a limitation of PDF or Release 22 in general? It affects every MSO in the folio, and there are dozens of them.

Hold fire on that for the moment, Bob. In tests, I find that if I upload an article on its own or with just a few other articles, the MSO rotation trick works, but it doesn't work when that same article is uploaded to a folio containing LOTS of articles.

It is most frustrating. I've suffered endless problems with this folio, with interactivity and autoplay slideshows displaying correctly when previewed locally the Desktop or via cable on my iPad, but then not working when downloaded from the cloud server. One article even seems to generate a page thumbnail not of the page but of an object state, and for that matter an object state that I deleted from the layout more than a week ago. I have recreated the slideshows and, in several cases, recreated entire layouts from scratch again and again, but no joy. I have tried saving as IDML to clean things up. I have deleted folios, created new ones and uploaded everything all over again.

These actions helped fix some issues but not others. Faced with a 3am deadline, I had to strip out certain things (such as autoplay slideshows that weren't playing) and simply give up on getting MSOs to remember their states when rotating the iPad. Ah well.
