When opening this site I can't see the menus. I see the word "Expand" side de menu name.
If I use Firefox then I have no problems.
Confirmed with r16938.
They must be sniffing for Safari directly because spoofing as Mozilla in both the nightlies and Safari 2.0.4 results in perfectly working menus like Firefox.
Moving to Evangelism component per the above comment.
Hmm, I'm getting different results:
1) shipping Safari doesn't work regardless of spoofing;
2) ToT works regardless of spoofing.
So, looks like the site has changed. Closing, because I could not find any problems with ToT. Reporter, could you please verify that nightly builds from <http://nightly.webkit.org> work for you?
