Packaged InDesign files lagging when more than one open
InDesign has become unusable due to lagging when more than one InDesign document is open, but ONLY if these are from packaged files. As standalone documents before packaging they work fine.
I have been doing a lot of testing and simplified it down so much that I can just have one text box with a few words in the document (default Minion Pro font) and I still get lagging.
Lagging includes:
Can't select text straight away
Typing text
Moving objects is difficult
Wheel spinning on and off
Delay selecting tools
= basically unusable!
This is not an issue if only one of the packaged documents is open. Unfortunately my job requires more than one file open a majority of the time.
It has taken almost 4 weeks to understand this is the exact issue and I'm at a loss. Any ideas on how to fix?
