We are on 5.3 (11/13/2006 build) and are having a lot of problems with the form elements when using Firefox (IE seems fine in all cases).   For instance, with Firefox we cannot type into text boxes, select values on lists, nor select values for the radio buttons and checkboxes.   If you give me an e-mail address to which I can send information privately, I can give you a login account to our site so you can recreate this behavior yourself.   Is there a configuration change we need to make?   Thanks in advance.
