It flashes for a second in the div but then opens in a new page in IE

[starp25]

1) Script Title: Ajax Tabs Content script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...axtabscontent/

3) Describe problem:

The website is http://ipegit.siteburg.com/ the problem is that it opens for a split second in the right div but the page loads the a href link in a seperate page not within the div, this is only in IE (it works like a charm in FF)
