I've been doing OK with Knoppix 4.0 live CD and live DVD for 6 months now. I am now trying to get Knoppix 5.0 live dvd to work on my PC but nothing much works: (I have a diskless Pentium with a flash memory stick).

1) All cheat codes are ignored. Therefore my configuration file isn't found.
2) Control settings are fixed and can't be changed. Therefore I am stuck at a screen resolution of 640x480 with a 20" monitor.
3) K menu pages auto paint with no margin so open when I don't want them and they can't be closed without selecting an unwanted link.

Do I have a defective DVD? Does 5.1 solve any of these problems? 5.0 appears to be a massive step backwards from 4.0, so please tell me I am missing some little obvious thing I must do to make it all cooperate! Thanks.
