Sixupdater is a crappy piece of bloatware allright. Crummy toolbars and stuff are being shipped with a lot of tools these days (MicroTorrent, Foxit Reader to name 2 :\ ).
I find I need to have another pile of wood in my active inventory when I light the fire. Then I move the raw meat from backpack to active inventory and BBQ it. (Well not anymore since I can't get any wood because I refuse to carry around a giant 10 slot axe..).
