JQyeryUI Calendar displays an extra box

I am trying to write a page with 2 calendars and I get a strange artifact.

Dates <input id="dates" type="textbox" />
From: <div id="dtFrom" class="datepicker"></div>
To: <div id="dtTo" class="datepicker"></div>
Some more text

Here is the javascript

$("#dtFrom").datepicker();
$("#dtTo").datepicker();​

But when I render it I get an extra thin box at the bottom after 'some more text'.
Is it not the right way to use the calendar?
