KDE3, KDE4, Plasma, Twinview == Not Good

Dear Lazyweb, This frustrates me and makes me all kinds of sad… For some reason, whenever I start my normal KDE3 session, plasma and KDE4 insists on starting up as well. So I get KDE3’s kicker and KDE4’s plasma stacked, which is less than fun and not quite useful. Also, I can’t get plasma/kwin4/kde4 to play nicely with twinview. I have an external monitor that runs @1280x960 and my laptop screen that runs @1280x800. I think it’s confusing plasma, and it looks like this. =:( Anyone know why or how to make it better?
