Text lag/slow when Documents Folder is present (package)
Since 15.03 there is a Text lag after opening documents that are in a folder that has a Documents folder. This delay has gotten worse in 15.1. If you're working from packaged InDesign folder, try deleting the document fonts folder inside it. Lagging was caused because of a double up in fonts on my computer. This took a month of testing by myelf and IT team to finally figure out!
Yes, same issue here. Document Fonts folder slows everything down to an unusable state. Editing text boxes is impossible, and it even gets stuck in the Text tool. Can't go back to the select tool.
