Troubles logging on and off

I seem to be having some troubles logging off certain characters, in that when I log off I go back to the world select screen for a second and then d/c. I don't think it relates to class, as one is an explorer and the other is a Cygnus. The only thing they have in common is that they are both the first characters on the left of their respective select screens. Is this a common problem, or just me?

Edit: Alright scratch that, it seems to happen on almost all my characters. Just not all the time.
