Can’t toggle between Visual and Text or Screen Options

If I am right, a plugin might be causing the issue.

To detect the cause of problem, you must know when did this problem started occuring? Did you start after you upgraded WordPress, or after you activated a certain plugin?

Also if you’re using WordPress version 3.5, that version does have this issue. Check here, it should have been fixed in 3.5.1.

What next?

Well, I will suggest you to upgrade the version if you’ve not already and/or try deactivating plugins one by one and checking if problem got solved.
