Just upgraded to BIAB2011 for Mac (from 2010 and going way back), and am having a weird problem in the notation window. Probably just some stupid little setting I'm missing, but very frustrating.

I'm in the editable notation (though same thing happens in piano roll). When I click on a note and try to drag it to another pitch, one of two things happens -- either nothing at all, or it adds a new note on top of the old one. Same thing happens if I use the Note Edit window -- if I option click on a note and change it, say from E5 to D5, it just adds the D5 on top of the E5. If I hit the delete button, nothing happens -- the Note Edit window closes, but the note is not deleted.

It's acting like the existing notes aren't there (I entered them via the wizard and the qwerty keyboard). If I click to add a note, I can edit that note just fine, but not the ones entered via the wizard.

Any ideas?
