I'm noticing that when I move some tracks into my monitored folders, it seems to not import one of the tracks. It always seems to be the last alphabetized track (I start my file names with a catalog number, and it's always the last number that doesn't get added). When I close/re-open MM Fusion or when I add files by monitoring folders, it will catch the last track and add it.

This has happened to me for a while, so it's not something new with 7.1.1.
