Damned ''Turn on accessibility This box keeps popping up on my computer! It won't go away no matter which box I click on in it! I end up having to turn my computer off and back on to get rid of it -- until it decides to pop up again! It's gotten to where I DON'T want to use Dropbox, I just want to get rid of it for good! How can I wipe it from my drive and never have to bother with it again!?
