1. to put the indd and icma and icml files all in the same Dropbox
2. to only open InCopy access to the main text in which the cross references are placed. All the text boxes to which they refer remain closed (these are figure captions, which is a pain because the editor does need to add some captions for me...). Once I open them and they are edited in InCopy, the cross reference is lost.
Anyone has a better idea for working on this document, I'd be very happy!
