CC 2017 seems to have slowed down drastically across all the major applications (Photoshop, Illustrator, After Effects) on Sierra. InDesign seems as if it doesn't want to start at all: I double clicked the app at 4:01pm; it took till 4:06 to get past the splash screen, and until 4:20(!) before I could start a new document and go to work. What is going on? I have tried reinstalling using the uninstaller in the InDesign folder, and by using the CC menu. I have deleted prefs and cache, and removed the Suitcase plugin (the only plugin I'm using).
