Not enough information.
What version of JQM? Can you share some code?
I don't know what you mean by "auto scrolling".
I don't know what you mean by "before the submit button is pressed".
Where is the page submitted to?
Are your pages unusually large?
Are you doing synchronous Ajax requests? (It's a no-no! Not just for JQM.)
Did you use data-ajax="false" or rel="external"?
