I just installed MacOS Sierra this evening. I opened a database and all seemed okay. I started making some minor changes to several forms. When I chose one form, I received a dialog box saying
Internal Error
An uncaught exception was raised. Choose “Continue” to continue running in an inconsistent state. Choose “Crash” to halt the application andfile a bug with Crash Reporter. Choosing “Crash” will result in the loss of all unsaved data.
I have never seen this alert before, so I guess it is related to Sierra. Here’s the screen shot of the dialog box.
Here’s the text reported when I chose Show Details:
