This is my first forum post so I would like to apologize if I'm asking this in the wrong place and also to thank PG Music for making such a fantastic program! Thank you very much!

Something happened today, maybe as a result of the latest patch, or some other magic, but it broke my chief way of navigating between the chords: with the arrow keys and selecting while holding shift. However now if i hold shift while moving the arrow keys i get this yellow error message http://i.imgur.com/tJYYcQf.png

I kept searching in all the preferences, but couldn't find anything. This makes editing chords much muuch harder/a pain to always have to use the mouse to select groups of chords for copy/pasting, so I would really appreciate your help. Thank you in advance.
