Problem using contact form in widgets

After we updated to the latest version of WordPress and your Contact Form, we noticed a strange behavior. While the forms located on the main area of a post still worked fine, a contact form placed in a widget now inserted about 8 inches of blank lines before displaying the fields for the user to respond. We had not altered the widget. A professional consultant verified this behavior and suggested we contact you to ask if this was because of a change in WordPress or your Contact Form code. Unfortunately the site owners insisted that I remove the offending widget, but if you need to see an example, I may be able to provide one. The actual text widget code was
‘<div class=”shadow”>
<p>
<div style=”border:1px solid #000;padding:5px;”>
[si-contact-form form=’4′]
</div>
</p>
</div>’
but even when the shadow div and paragraph elements were removed, the extra space remained.
