I keep being asked for my Mac password every time I rename/move files on Dropbox

Hi Nancy, 

Thanks for the reply. I checked the things you asked.

The filepath is: Macintosh HD/Users/XXX/Dropbox

No specific update has been taken place, just like I told you earlier I got the same things installed and same updates on my macbook, where everything works fine. 

All the permissions are there!

I found out something new. So when I do the following things it will give me a popup from Finder where it say something like: Finder wants to change the name of "...". Enter your password to allow this.

• When changing a folder or item
• When moving an item towards another folder in Dropbox
• When moving an item out of Dropbox
  
  

This is only happening in the finder. When I go online, browser, it works.

But when I copy a total new item inside a folder which was previous lets say on my desktop. It works. I can just copy it in there. Also I can change the name of that item, or move it somewhere else. How on earth.
