Screen Options tab missing

Hello

Ive just installed a fresh version of WordPress 3.1, and the Screen Options tab seems to be missing…or perhaps it’s hidden by the new Jetpack banner?…so I cant turn off the commenting option for static pages.

Has anyone else encountered this problem?

Is there a way to make the Screen Options tab visible again and/or remove the Jetpack banner, and see if the Screen Option tab is hidden underneath?

Any help much appreciated!

Will
