Hi there. I'm currently using InDesign CC 2015 on my computer at work. Unfortunately in the past few days it's been having a 1-2.5 second delay on every click, highlight, drag, and any other action performed. I've cleared out my preferences for InDesign as well as restarted the program and my computer and everything is up to date. What else can be the issue and how can I solve it? Thanks.
Try using the Activity Monitor to turn off the CC Libraries.
I think that really helped! Thanks, Larry!
