Product and version: FileMaker 16 compared to 15
OS and version: Mac OS X Sierra
Browser and version N/A
Hardware: MacBook Pro, iMac, Mac mini
In layout mode
In 16: When a field has a button Action it is impossible to see it's attributes when right clicking or in the inspector - not even the name of the field.
In 15: It is working, you can se everything.
How to replicate: Open a file with a field that is a button. Not grouped with anything else. In 16 try seing the attributes in Inspector or by Right clicking.
Workaround: Ungroup ... thereby loosing the button function, do what you need to do and then re-enable it as a button. Or do not use fields as buttons .. which is also a good solution in many cases as field buttons may confuse the user ... you can make a button bar with calculated names from fields if you need a button with field data names.
I am adding a movie showing the same file and layout in FMPA 16 and FMPA 15 (shared).
Is it a bug or is it a missing feature we will have to learn to live without ... not sure.
