Thx. Rollback will only be the last escape. i think theres another way..
Found out, that the site AutoLoggs me everytime i link to an Page with an Parameter...

i.e: a link to www.sfg.com/user.php works fine.
but a link to www.sfg.com/user.php?op=logout will cause a autologin...
All in all: everytime i open a link to an page with an parameter -->
xyz.com/link?parameter
the system reloggs me
