Strange jQuery UI issue with IE

Strange jQuery UI issue with IE


Hi
I have create a Drupal site using JQuery UI on my Red Hat box +
FireFox.
Just curious I went to a Window box, and brought up IE 7 to my site,
and all the jQuery UI components and formatting were non-existent.
On the same Windows box, I brought up FireFox and everything was fine!
Then from the same IE 7 browser, I went to the http://jqueryui.com/demos/datepicker/
site, and the demos worked fine.
Is there special scripts (javascript/CSS) I must add to make my site
work with these browsers?
I am using:
css/redmond/jquery-ui-1.7.1.custom.css
js/jquery-1.3.2.min.js
js/jquery-ui-1.7.1.custom.min.js
Thanks
