If you paste your backed up settings into ATA 3.6.7 and click "Import Settings" you get the message "Import Successful". But no, it is not! You still have to hit the big green "Save Changes" button at the bottom.
I propose this as a sticky for newbies.
I also propose this as a change for the next update: either 1) make the "Import Settings" button also do a "Save Changes" simultaneously or 2) make the message read "Import Pending: Click Save Changes Below to Finalize".
