This was how it worked in FMP 13. Maybe they chose to change this in FMP 14 and failed to update the FTS text accordingly.
Or they goofed with FileMaker 14.
I rather prefer that FMP NOT add that script automatically. I kept getting multiple identical scripts with each new iOS layout in 13 and would rather add the zoom lock script step myself--often as part of a larger script that is performed OnLayoutEnter.
Thank you for your post.
The automatic script creation for iOS layouts was removed in FileMaker 14, and the FTS Basics was not updated. I have forwarded this information to the appropriate person to make sure future revisions of the FTS Basics is correct.
