So I was part of the huge chorus of people last year asking Dropbox to bring back the Time Left to Sync status bar back to the Desktop App after removing it without warning. Well... just like clockwork a year later they made it disappear AGAIN!!!
Yes I know I can hover my mouse arrow over the little icon on the Windows Task Bar, but I don't want to do that. I just want to have the upload box open and the status bar at the bottom back where it was so I can monitor my uploads.
Why can't you guys just leave these things alone and stop messing with our workflow???
Rich is indeed right that there currently isn't a way to disable the desktop app from automatically upgrading I'm afraid, which you can check out more info on from here.
When you turned on the "Early releases" option and installed the beta version previously, the app would automatically update to the latest beta version available.
As it could just be an issue that you're having with the beta build, or you'd like to stop using beta builds in the future, then I'd suggest switching back to using the stable versions by toggling off the "Early releases" option.
