Missing scroll bar on InfoPath form in SharePoint

We created an InfoPath form and published it to a list.  Our goal is to email a link directly to the form for users that will be filling it out so all they see is the form.  The URL is quite long and ugly but it does open the form in a non-dialog box but when it does the scroll bar always goes missing in the browser.  This usually happens in Internet Explorer and refreshing the page several times sometimes causes the scroll bar to become visible.

Has anyone seen this before?
