as the compiz+lxde combination has a bug causing all tabs from all desktops to be allways visible, even when you disable it at the preferences I decided to try openbox just for fun.

So installed some openbox packages like obconf and removed compiz. then I went to desktop session settings to replace
Code:
compiz --replace
with
Code:
openbox --replace
at the next bootup I was greated by a desktop without window manager. The only solution was to go to lxterminal and type "openbox --replace".
Scratching my head trying to figure out what I did wrong I fired up desktop session settings. The problem turned out to be that knoppix resetted the openbox --replace line to it's default compiz --replace line.

Why the hell is this hapening (to me) again, there were persistency problems in the past and that was solved by following this:

I am running the cd version of knoppix 6.4.3 (have yet to try it on the 6.4.4 usb)
