Themeroller Bug

Themeroller Bug


I'm not sure if something has changed, but the dialog box on the
themeroller no longer shows the background. That is to say, the
dialog opens up, it opens up and shows the dialog correctly, but the
background no longer shows up. Is this a bug?
I've tried it on:
Mac OS X 10.5.7, FF 3.0.10
Windows XP SP3, IE7
go to http://jqueryui.com/themeroller/
and click on the "Open Dialog" box and no modal background shows.
A few weeks ago, this was not the case.
