How do I stop the Dropbox desktop app from opening whenever I start my computer?

Hey MH19 - thanks for using Dropbox and happy Monday!

This is the Dropbox desktop app's interface, not a pop-up notification. If you'd like to, you can turn off the option that enables the app to start automatically whenever you boot your computer through the app's preferences, under the General tab. 

I hope this helps and please let me know if you have any follow-up questions. 

Thank you Walter! 

So the only way to disable the appearance of this interface is by disconnecting dropbox from startup completely? 

I've had dropbox connected to startup for years. It's only in the last couple months that this disruptive box appears. 

Hey MH19! If you follow Walter’s suggestion and turn the automatic startup Off and then On again, does the issue persist?

Thanks for your suggestion Nancy! Yes, I tried that and the problem does persist.

Hey MH19, I hope it's okay for me to jump in here as well.

Does the system tray window remain open even if you click out of it?

Can you also hover over the small Dropbox icon in the system tray and let us know the Dropbox app version you're using?

Thanks Hannah! Yes, sure, all help is welcome.
It's version 226.4.5094
I can click out of it, but part of what makes it bothersome is there's no "X" button. To get out of it I have to take two or three steps. Not such a big problem given the state of the world these days, I know. But maybe one that I can find a solution to?

Usually you only need to click once anywhere outside of the window to close it. Does that not happen?

Thanks Rich! 

No. I need to click somewhere to make the toolbar visible on top of it. And then click the dropbox icon to minimize the interface box. 

Hi MH19​,

Thanks for reaching out on the Community. I've looked into this with the relevant team within Dropbox and they have informed me that this is possibly a bug and that they are fixing it as we speak.

As soon as there is an update, I will let you know!
