InCopy becomes very slow when a cross-linked document is closed
InCopy 14.4, MacOS Mojave 10.14.4
I work on an InCopy document that was assigned to me from InDesign. I want to create a cross reference to another document. Hereto I open that document, check out the content, switch back to my working document and create the references.
After this I close the referred document and this freezes InCopy. What I see is that the CC-synchronization starts to blink constantly in my top bar. Every mouse click or cursor movement takes appr. 45 seconds to take effect.
This is unworkable.
