The tracts are not frozen and I was selecting the generate icon. I also tried right clicking on a track and selecting Regenerate from the drop down. I previously had deleted the offending chords but they are still playing.
Thanks for the tips. I did learn about freezing tracts in the meantime.
What else could be going on?
P.S. Windows 7, 64 bit, BIAB 2013 on the external drive.
