SSI login/logout problem

[CapadY]

I have my own site with some frames.

In one of those frames I have al call to the login script from SSI.php, writen like ssi_login('mysite/index.php', 'echo') and the SMF forum is located at mysite/forum/

Everytime I log in or Log out the complete SMF forum is shown in the frame where only the login/logout boxes should be shown. How get I rid of showing the complete forum ?

Loging in and out is working properly.

By the way, forum is a completely clean installation of RC3. So, no MOD's, no language packages and all settings on default. It's installed local so no link can be given.
