The demos on api.jquery.com are broken - they are either blank or don't do anything (ie: mouse events). The demos don't work when I try them locally either. I am able to load other working jquery pages on the web (ie: jqueryui.com), but not the demos or anything I'm trying to build. This has been going on for some time and it's really frustrating.
I'm using Safari 4.0.5 (just upgraded to 5.0 & it doesn't work either) and Firefox 3.6.3 on Mac OS 10.5.8.
