Widgets – multiple js errors

I am getting multiple javascript errors when I click on the properties button for most of my widgets.

Linux + PHP 4.3.4 + Apache 2.0.49 + mod_php
WordPress 2.0.3

I’ve read most of the posts on this subject – I copied the scriptaculous under wp-plugins/js and I don’t have any admin theming (i.e. Tiger etc)

On loading wp-admin/themes.php?page=widgets/widgets.php I get:

Warning: Unknown property 'zoom'. Declaration dropped.

Line: 605

Warning: Unknown property '-khtml-opacity'. Declaration dropped.

Error: $("pagespopper") has no properties

It smells like a missing include or a badly behaved widget – but seems generic enough that other people are having the same issues.

Same problems with IE, Firefox 1.5, Firefox Bon Echo..

Any ideas?

(I’ll be dropping 2.0.4 on tomorrow for the bug hunt..)
