This is not a big deal but when I hit "cmd-shift-F" to expand the frame for easier reading, it reacts slowly and goes back and forth from the original to the expanded screen. It eventually expands but it was not doing this in the past. I am running Logos Bible Software 4.2b SR-1 (4.22.5.1109). This has occurred before and after the latest update. Again, it is not a big deal but I am hoping someone might have a suggestion.
