[Typo3] Linking to a Site behind a Login proved Site don't work?

[hitcher at wcm4u.de]

Hi all,
first sorry for my English...
I've a Problem with the New Login Box and the FE User Registration.
When i want to link to a Site in the Login-proved area, i get the Typo3
Error: The requested page was not accessible!
Is that normal?
I want to get the Loginscreen, do the login and get then the linked
site. How can i get this and is that possible?
Please help...
With best regards
Hitcher
