[3.0]Upload/Insert On Post. Tag, Category Issues

Hello there!

After I upgrade my wordpress to 3.0 I’m having some problems with these options: Upload/Insert Imagem, Video, Audio, Media. Instead of opening the box on the same page as on edit posts, pages or whatever, it opens like a new page. I can upload it normaly but it mess up with the option to Insert Into Post, can be one imagem or a galery of images. It wont go back to the Edit a Post page.

I’m having problems with TAG too, I don’t stick with the post after clicking on Add.

And I can’t add a New Category while posting a post.
