Jquey tabs delaying when the html loads.

Question

Hi guys

I made the front end (xhtml, css and jquery) of this website, you can see it live here: http://news.lifecooler.com/lifecoolernews/jquery/index.html

The guys who develop the databases integration and all the dev work made this: http://www.lifecooler.com/edicoes/lifecooler/index.asp

If you see in the html version the tabs load quickly without any delay but in the final version the delay appears.

Could someone help me out to fix this delay?

Thanks in advance.
