Preserving Flash Form data if Back Button Is Used After Submission Produces Error

I programmed a multipaged paper work into a Flash Tab formatted form. My users love it. However, they do not like the fact if they submit the record and it errors out, they can not hit the back button to correct it. They have to re-enter all the data. Is there a way I can fix this? Hitting the back button produces the need to refresh the page message. Once you do that, the data is gone.

TIA!
