Problem with cfwindow and cfinput datefield

If you have a cfform that contains a cfinput type datefield that is displayed in a cfwindow there is a problem when you scroll the cfwindow.

That is if the form content causes the cfwindow to have scroll bar when you scroll the cfinput datefield stays where it is while the rest of the form scrolls with the window.

Does anyone have any idea how to fix this.

The code being used is as follows

<cfwindow
     width="800"
        height="200"
        name="myWindow"
        center="true"
        title="Test Window"
        modal="true"
        initshow="true">

        <br>
        <cfform name="mycfform1">
            <div style="float:left;">Date 1: </div>
            <cfinput type="datefield" name="mydate1"><br><br><br>
            <div style="float:left;">Date 2: </div>
            <cfinput type="datefield" name="mydate2" value="15/1/2007"><br><br><br>
            <div style="float:left;">Date 3: </div>
            <cfinput type="datefield" name="mydate3" required="yes"><br><br><br>
            <div style="float:left;">Date 4: </div>
            <cfinput type="datefield" name="mydate4" required="no"><br><br><br>
            <br>
            <div style="float:left;">Date 1: </div>
            <cfinput type="datefield" name="mydate5" mask="dd/mm/yyyy">
                (dd/mm/yyyy)<br><br><br>
            <div style="float:left;">Date 2: </div>
            <cfinput type="datefield" name="mydate6" mask="mm/dd/yyyy">
                (mm/dd/yyyy)<br><br><br>
            <div style="float:left;">Date 3: </div>
            <cfinput type="datefield" name="mydate7" mask="d/m/yy">
                (d/m/yy)<br><br><br>
            <div style="float:left;">Date 4: </div>
            <cfinput type="datefield" name="mydate8" mask="m/d/yy">
                (m/d/yy)<br><br><br>
        </cfform>
</cfwindow>
