ReportViewer Calendar button Click does not show calendar

ReportViewer Calendar button Click does not show calendar

I have a reportviewer on a page which is grabbing a report from a report server. the page is basically just a dropdownlist and a reportviewer control. The problem I have is that in the report the user have to provide the dates for teh report. The reportviewer automatically adds the textbox for the date entry and a calendar icon in front of it so the user can select the date. if I look at this page  in FireFox, when you click on the calendar button created by the reportviewer, the calendar control show up momentrily and dispappears. If you look at the same page in IE 7.0 nothing happens other than the page appears to be submitted. Does any body have any ideas on how to go about troubleshooting this bug?

Thanks
