I'm using InDesign CC (184.108.40.206), and I've been working on large file for a while. All of a sudden, it no longer saves. I hit Ctrl+S, thinking I'm saving, but when I go to the menu, Save is grayed out. Fortunately, Save As is working, so I am saving as a new version, just in case. I can also Save As a previous version, overwriting it, but Save stopped working.
Why can't I save using the "Save" menu command or Ctrl+S?
Thanks. Apparently, InDesign is smarter than I am.
