Two or three times a week at precisely 7am, I get a popup from Dropbox asking if I want to delete a particular file from Dropbox and everywhere else. There are two or three different filenames that rotate through this message depending on the day.

I don't know why it keeps asking me this. I don't want to delete any files, let alone from "everywhere."
I click the checkbox "don't ask me this again" and then the "cancel" button every time. The box disappears but will come back in a few days with a different file name and I go through the same routine again. The following week, the same important file name will come back in this popup message.
How do I stop this insanity?
Thanks, Edgar
