I was happily entering text onto a score, thus: drag 'text' symbol from part box to score, write word, hit 'tab' to go to next note. This has now changed, and hitting Tab no longer moves the cursor to the next note. Now, for no apparent reason, when I hit 'tab' the word is greyed out, and when I enter a letter, Logic goes to a completely unexpected and unpredictable menu option. For example, letter 'b' gives me the bin. What has happened? How do I fix this? Thanks in advance
