SUMMARY If the PDF-File was modified by another program, Save As … is ALSO disabled. I had to discard and redo all my own changes, because I couldn't SAVE AS – which should be allowed. STEPS TO REPRODUCE 1. Open PDF and add annotations 2. Have another Program modify the original PDF (e.g. a cloud application) while it is still open in ocular 3. Have Ocular NOT Reload (because you want to keep your own annotations(!)) 4. SAVE AS … is denied! OBSERVED RESULT SAVE AS has become impossible
