I recently upgraded from Filemaker 11 to Filemaker 12 and have found a difference in behavior when I display a custom dialog. When a record is saved I run a script to validate that all required fields have been entered. If there is an error I show a dialog box with an error message. In Filemaker 12, the current layout turns completely blank (white) when the dialog box is displayed. Once a selection is made on the dialog box, the layout redisplays properly. How can I keep the screen from blanking out when displaying a custom dialog? When I run the same script using the debugger, this does not happen.
