Just the other day my Acrobat DC suddenly started popping up a "recent files" window every single time I go to do anything on my computer, even do a google search or look at email, if Acrobat is open. This is incredibly annoying because it stops everything I'm doing and I have to close that window before I can keep going. I don't even need a recent files list but this new popup is driving me nuts. If you don't make it possible to disable it or just get rid of it altogether I'm switching to another app.
