Button calls script to go to a record by ID, script parameter for desired record ID. Works in FileMaker 14 and earlier, crashes FileMaker 15.
Similar button calling the same script in different layout works in FileMaker 15.
Change button in the first layout to go to related record and that works.
This problem occurs with different layouts, different buttons, different layouts/records to go to. Seems to be no pattern. IN all cases the buttons/scripts work fine in FileMaker 14 and earlier.
