This diary generation message occurs before processing a BOXFIT token, if there is no text overflow to start with and if the warn if no overflow in boxfit generation option is set to true (the default).
As the behavior of this token depends on the version of QuarkXPress that you are using, the present message will be issued under different circumstances, depending on the version of QuarkXPress that you are using.
Using InDesign or QuarkXPress 2016-2025
When using any version of InDesign or QuarkXPress 2016-2025, this message will only be generated for a box containing a BOXFIT token, with a step size of more than 2 points, and that does not have text overflow initially.
Using QuarkXPress 5-2015
When using QuarkXPress 5-2015, this message will be generated for any box containing a BoxFit token, and that does not have text overflow initially. If you wish to have the exact same functionality, but never see this message, then use the [BOXGROW] token instead.
