Is Notebooks an app? Do you have a link?
Hm... strange. How do you import these files? Dropbox, iTunes sync? Will they open fine in Textedit? How about the other way around -- do files created in Ulysses open fine in Notebooks?
(On a sidenote, and not meant as a rant against Notebooks in particular, but boy do I hate apps with names like that. It may be a language issue, and I know Apple is encouraging the use of such names, but it's so very confusing to talk about notebooks created in Notebooks, when they could've easily called it SchmidNotes or such... argh, never mind.)
