login/logout problem with WP 3.3.2

Hello All,

After I upgraded to 3.3.2 I am having this problem:
I am already logged in, but WP still shows “login” but not “logout” under the META panel at the right side of the FrontPage.

And when I clicked “Leave a Comment”, it still asks me to:
You must be logged in to post a comment.
And I login again, does not help.

Is this a bug?

Regards
