If you:
1. drag a sequence file into IGB, it automatically opens as the reference sequence in the coordinate axis.
2. Opened from a file, it creates a track
3. Opened from a URL it opens as reference track
4. Opened Reference Sequence... opens as reference sequence.
*My advice for consistency is to ALWAYS open sequence files as tracks unless specifically "Open as Reference Sequence" (notice the inserted 'as' in the command). *
