[bitfolk] Screen on console

Hi All, Maybe it is me that have missed something (as usual), but it seems that I have a strange behaviour at (in? on? with?) the vps console. I can login as usual, and screen is starting up a shell on my vps. But if I detach the screen process from the console (with C^-a d for example), I am immediately logged out. At that stage I expected to get to the xen shell so I could control the state of my vps. But that does not happen. Anyone got any ideas as to why this is happening? Thanks, __ /ony
