Safari Issue with forms using display: none

There seems to be a safari specific problem with a web form i'm working on. On the submit of the form, I'm changing the display style property of the table that holds the form to none, since the form has a long upload time and I don't want the user to mess anything up. This works fine in IE and Firefox, but in safari, I get an error on my serverside page saying that none of the form fields were passed. I tried changing it to visibility: hidden instead of display, but that apparently has the same effect. Does anyone know a workaround for this, so I can hide my form elements, but still have them be passed?
