I'm encountering a frustrating issue. I have a 2007 form that has 60+ fields which are mostly check boxes and radio buttons. Advanced settings at the field level have postback set to always on the fields. I have a repeatable case where when a field is checked and the postback occurs, the firefox page will "jump" on what i am assuming is the page_load. This issue only happens in firefox not in IE. Tab orders for all of the fields are set and the form is constructed as multiple sections within a series of tables. Anyone have any thoughts as to why the page jumps on a postback ?
