If I print to pdf using Acrobat and choose a Custom Page Size, and then without closing the file, print again, the Page size defaults to Letter and I have to reenter the custom size. This does not happen in X5.
Inline graphics no longer export to AI properly. Now the graphic comes into Illustrator as a separate artboard -- one artboard for each instance of an inline graphic. Worked fine in X5.
An X5 file that had paragraph text using points for the leading and paragraph spacing moved when saved as an X7 file. The kicker is that it didn't move until I closed the file and reopened it. It doesn't matter if you choose to update text or not, it still happens. I got burned on that one when part of my text ended up under a black box, and it got cut off.
