Yast not starting upon VNC reconnect after reboot.

Hello, I am trying to do a remote install using VNC, installing SuSE 9.3 Professional. This all goes fine until Yast wants to do the first reboot. The machine reboots and after coming back up the console tells me to reconnect my VNC viewer and finish the installation. However, if i reconnect my viewer i just get an empty screen. It seems to be a gray pattern empty X screen with a mouse pointer. But Yast is not coming back to finish the install. Is this a known issue? Or is there anything i should check? Regards, Teun
