Dropbox requests (though doesn't seem to require, i.e. it runs without) accessibility/control computer permission (under Security -> Privacy).
Removing permission manually (requiring admin password), then rebooting, leads to permission being granted again. Which doesn't seem to be the way it should be, right?
Any idea what mechanism allows the app to grant itself Accessibility permission? Alternatively, if it's not Dropbox, but OSX itself, why would it change the value?
