Problems at shutdown screen

Most of the time, when I exit out of KDE3 and choose to either reboot or halt, the systems gets out of the GUI mode, gets right in the green screen where you see all the message that are suppose to scroll up and say something like "rebooting system . . blah blah", but the system kinds of is stuck there. It does not like to proceed once it gets out of the GUI. The only way to get the system to proceed with the shutdown or reboot is to hit the ENTER key. Otherwise it waits there forever. I have in the past fixed this by doing .... well I don't know.....it fixed itself earlier. I am not sure if it happens all the time, but I'd say most of the time.
