Using WIN 10 and 11 my screenshots always worked well, going to the folder Pictures/Screenshots after a brief dimming of the screen, which I interpreted as the taking of the screenshot. One day Dropobox started to stick its nose in and I always said the equivalent of "Get out! Get out! Get out!" Now I'm at the point where my screen no longer dims when I take a screenshot ("Fn-PrtSc" on my Lenovo laptop) and NO screenshot appears in "Pictures/Screenshots".
If Dropbox has taken over screenshots:
1. Where should I look to find them?
2. How do I make Dropbox stop this unwanted behavior?, and
3. Once I've corrected the problem, how do I get rid of Dropbox to prevent this from ever happening again?
Thanks!
p.s. My "Share screenshots using Dropbox" has always been unchecked.
