In the attached file using 3.3-RC, the frames are hidden when "Show invisible" or "Show frames" is unchecked. Both must be checked to see frames. As you are aware, frame visibility is controlled exclusively by the "Show frames" option. I was creating a bug report for this and was ready to press submit, but I was also double checking what was happening and realized it was only this score with the strange behavior. Any clues why this is happening?
