[support] How to prevent block-user from showing up in the left sidebar

[Sten]

Hi!

I have a problem with this block-user thing showing up in my sidebar. I 
only want the menu there and I haven't added it to sidebar block in the 
block settings, but still drupal can not help including it. When logged 
in it's only a name, but when not it's a whole login form, something I 
only want to have on the login page. Who do I get tis block out of my 
sidebar?!

thanks

Sten
