I switched to High Sierra 10.13 Beta (17A362a), which is supposed to be the final release before next week's public release. But as far as InDesign is concerned, High Sierra has been the Mojave Desert. I've tried everything suggested in this forum, and I still have to quit out of InDesign and restart it every couple of files.

I originally switched to InDesign 1.0 back at the beginning of time because Quark was making us use those ridiculous dongles. What morons. Now I'm starting to feel the same thing about Adobe and InDesign. They should have had this taken care of a few weeks after it was first reported.
