UI Tabs 1.7 Invalid argument on IE 7 and 8rc1


Hi,
I have recently upgraded a site to jQuery 1.3.2 and UI. 1.7 and I am
now getting an Invalid Argument error on a page which has UI tabs in
use. I am using the basic theme including all css files.
I have also noticed that this error also appears at the following url:
http://jqueryui.com/demos/tabs/
which would suggest it is not a problem with my code.
Is there a fix available for this yet?
Many thanks,
Dave
