InDesign freezes while Adding New/Editing Cross-References
1. InDesign 13.1 x64
2a. Select the text, go to Insert Cross References either via Type > Hyperlinks & Cross References or via the Cross References Panel.
2b. Select text that already has a cross reference, go to Cross-Reference Options either via Type > Hyperlinks and Cross References of the Cross References panel.
3. The New Cross-Reference or Edit Cross-Reference dialog box should open and function.
4. InDesign freezes and has to be force quit. I've waited as long as 20 minutes for the system to function properly before having to force it to quit.
