Hi John,
Touch Panel VIs do not support all of the functions or controls normally found on the LabVIEW palettes. In the LabVIEW Help, if you browse to Touch Panel Module >> Creating Touch Panel VIs, there are topics called "Designing PDA and Touch Panel User Interfaces" and "Developing PDA and Touch Panel Block Diagrams." Differences in Touch Panel controls, indicators, functions, properties, and methods are documented here.
When a VI is opened as part of a project under a touch panel target, the Functions and Controls palettes change to display only functions and objects that are supported. You will notice that some VIs, such as Merge Errors.vi, are missing, while others, such as PDA Error Handler.vi, are added. If the VI is opened outside of the project, it isn't specified as a Touch Panel VI so the standard palettes are visible. I prefer to develop my VIs under a touch panel target to make sure I am using supported functions.
Hope this helps clarify things.
