I have been dealing with this on a daily basis... several times a day. When viewing/editing PDFs from within Acrobat, with the Output Preview window open (either on the same screen or split) — Acrobat will crash every time that I forget to close the Preview window before viewing a different PDF (although I am doing the same task in both PDFs). I think it's slightly ridiculous to have to close the window every time.

Currently I have more than 200 single PDFs to edit (converting one spot color to another) and it is taking forever because Acrobat decides to quit about every 3rd or 4th document.

Why has this glitch not been fixed?
