I have a multi-page form with a "preview" button on the last page. Once the user preview the form, he/she should be able to use the browser's back button to edit the information. The problem is that when the user uses the back button, the values previously input do not show up in their fields.
This only happens in IE 5, and there is no problem in IE 6, and older versions of Netscape and Mozzilla. I have not tested IE lower than version 5.
