I should note that I'm also on LyX 2.2.0 (on Linux Mint). I tried grabbing a beamer file from an earlier version (but not as old as yours), put the cursor next to an image, and added a new frame without hassle. Cosmetics will indeed be different. Jurgen refactored the Beamer class massively in this version, and it may have been refactored once between when you wrote your three-year-old original file and this version. There's a conversion involved in getting your old presentation into LyX 2.2.0, not just cosmetic changes in the display, so it's possible you are correct that a version change is involved. That said, though, I've hit no speed bumps updating any of my presentations ... so far ... Since this issue may crop up again for you with some future update of an old file, you might want to take a moment (when you have one) to trim down to a minimal example and post it. Ideally, it would be best to cut down the file (and obfuscate the proprietary stuff) in an earlier version of LyX, so we can verify that the conversion issue is general and not specific to your setup. That requires having access to an older version though, so it might be too much work. Paul
