IWP - Browser back button displays previous record

[Bains]

Please pardon me if i sound dumb.

I have Filemaker server 7 running on Windows 2003 server. The databases are hosted using IWP and everything seemed to be working fine when i discovered this issue - Clicking on back button of the browser displays the previous record in IE6, even when i am logged as a Data Entry person.

The broswer back button in Firefox just refreshes the current record, But IE6 displays the previous record.

Is there any way of preventing this or disabling the browser's back button.

Thanks
