Hello Editrix1
Thanks for clarifying things. The action that you describe shouldn't change the settings from online to local. I was explaining that if you click on the file itself, it will change it from online to local. It will change it to local and then you would have to manually change it back to online after that.
It sounds like that you did not click on the file but you just right clicked the file to bring up the contextual menu to see the status, correct?
if it changed on that action, then something wrong. Did you notice what badge is shown on that file? is it a grey type cloud or is it green?
If it is indeed changing on just right-clicking the file then I suggest reinstalling Dropbox. I just did some test on my PC and it doesn't change it by the contextual menu.
Hopes this helps
