[otrs] Strange problem with 1.3b4

Hi, I've installed 1.3b4 on debian sarge and run through the initial configuration. Now after 2 or 3 selections within otrs when I click on something I get bounce somewhere else within otrs and I get a new session. These 'ghost' sessions never close ... I have a feeling I've messed up with permissions ... Does anyone have any suggestions as to how to rectify this ? Thanks Ruairi
