I am having trouble getting my region-based guidance with all of the guidance swaths included to be useable on our 750's, after having it work for the last few years.  I deleted last year's lines in the 750 and loading new guidance onto the 750 seems to go ok but when I try to use lines it will say no AB line defined or offline distance exceeded.  The 750 itself seems bogged down when trying to load some of the fields especially if they are further from where the tractor is sitting. If I load a single AB line with no other swaths or a boundary that seems to work.  Going to check with AgLeader tomorrow but curious if others are having issues, wondering if there's a bug with SMS Advanced 26.00.
