When the form is viewed in FF or Chrome, everything looks as it should. When it is viewed in IE8 or IE9 (and presumably, IE7) the last field is slightly higher. (see here: http://imgur.com/FIoR0 ) Additionally, there is much more space between the last line of fields and the submit button. Any idea what causes this or how it can be fixed/avoided?
