With the newest update 16.3.2 , my Indesign is running INSANELY slow. I had an Adobe engineer look at my program, but we couldnt figure it out. One of my workers had the same problem. I have a monitor plugged in for my MacBook, and I have the color settings to Apple RGB, but that hasn't helped either. I had a third party font book, Suite Case Fusion, but I deleted it just incase that was the issue. Reset my preferences as well. Nothing has been fixed.
