Hi Pat,

If you are loading the same file as saved previously at the last close, then RB does not initiate the BIAB functions because the Style name has not changed. However, should you change file and the STYLE name changes, RB does then initiate the BIAB functions automatically whether or not you intend to generate BIAB tracks.

For this reason, I have chosen a Style name which I use for all the files in development including $Options.seq to ensure that these BIAB processes are not activated unless required.
