[Typo3] Problems with frontend when logged in backend

[yetihehe]

Hi,

When I'm logged in typo3 backend I can view ony cached pages, others don't
even show. But when I have backend open in one window and front in second
(two processes) it works. The same, when backend is open in FF, and front in
MSIE. Any ideas what could be wrong? I think this could be something with
session.
