I have one user who has somehow changed their toolbar in Horde. Also, they are unable to enable Previews. (They can only click on a subject to be directed to a new page with the email as opposed to having the frame below the list show the email.) I've attached two screenshots. #1 shows the problem account and #2 shows a working account. Any tips?
