jquery radio buttons don't work in Safari (fine in Firefox)

Question

check out this page in firefox and safari: http://jqueryui.com/demos/button/#radio

the radio buttons example looks great in firefox, but comes up as regular radio buttons in safari (in fact none of the examples on that page work). any idea what the bug is in safari and how to fix it? or is it just my computer? javascript is enabled.

thanks.

Answer 1

Safari version 4: works great.

Answer 2

My radio buttons don't work in Safari or IE with Windows 7. Both worked fine in XP.
