Product and version Filemaker Pro v.13 - v.14
OS and version: Mac OS 10.10 - 10.11
Description: A solution with an external ODBC datasource crashes at startup if the ODBC datasource is unavailable. Fields from the related ODBC datasource are present on the startup layout so the solution immediately prompts for the ODBC login credentials. Selecting "Cancel" causes Filemaker Pro to immediately crash.
How to replicate: As above
Workaround: Open the database with Filemaker Pro v.12. Dismiss the ODBC login dialog ("Cancel"). This does not crash with FMP v.12. Delete the ODBC external data source reference. The file is now usable again on FMP v.13 or v.14.
