I upgraded to WordPress 3.0 from 2.9.2 earlier today. Everything went extremely well with the upgrade and the new version is quite simply beautiful. I did run into a bug though on the post/edit post page.
I can no longer move the panes around to arrange them and the panes do not collapse. Also on this page the screen options tab and the help tab does not open up. It almost appears as if the ajax features are not working at all.
The weird thing is the ajax works on every other part of the site except in the Post/Edit Post pages.
I checked out WordPress Trac but I am new to this whole process so I might just be searching the wrong parameters. Please help... anyone!
