Troubleshooting: I'm editing data using Favorites contained within a Stored Display. Why does it sometimes take a long time to start an editing session?
It make take longer to start an editing session if you are editing data within a Stored Display that contains feature classes with a relationship to table(s) that are not included with your Stored Display. You can decrease the time it takes to start an editing session by storing all related tables along with your Stored Display. To do this, simply use the Add Data command found on the Standard toolbar to add related tables to the Stored Display and Save the Stored Display.
The example below shows a feature class possessing a relationship with two tables (Assembly, Joint Use Attachment):
Viewing the Features tab, we see these tables are stored with the Stored Display.
