Redirected when trying to edit post in 2.0

Hi – I just upgraded this morning, and I’m having trouble with editing my posts. If I go to the manage tab, and click edit on one of my posts, I see the editor momentarily but then I’m redirected to the permalink for the post almost instantly. The only workaround I’ve found is to hit the “stop” button on my browser really fast. Any ideas for a smarter solution?
