CF blocks Dropbox

Hi! My Dropbox works OK only when I have Comodo Firewall disabled. It gives no popups about the Dropbox in any other mode. In all modes except “disabled” Dropbox just don’t connect to the Internet. How can I fix it?

Thank you.

Found a solution, though not the reason.

  1. Exit Dropbox.
  2. Purge Rules for FW
  3. Delete all rules for the Dropbox in FW
  4. Run Dropbox, make sure that it’s syncing
  5. Allow Dropbox if FW asks

I suspect the reason is that Dropbox is actually constantly upgrading. So the program is changed and it get blocked.
