I've came across an unexpected behavior when using popovers (FileMaker Pro 16.0.2 on Windows 10).
1. Several times it happened that the popover did not open when clicking on the popover button. When I clicked a second time on the popover button, the popover content pane opened; however, I could not click on the buttons inside the content pane. Using the script debugger I found out, that a script attached to a button wouldn't even start to run.
2. When I switched from one record to another one, the popover stayed open, and the content would not change.
Each time this happened, I had to close FileMaker completely (not just closing the file and open it again). Then, everything worked as expected.
The popover button is located in the top navigation part, on a layout using form view. There is no interactive container field on the layout.
Any hints are highly appreciated.
