ok, for some reason, over the past week or so (well it's happened for months but much more this week) I'll be using finder, doing something standard like moving a file or opening a folder and i'll get the spinning wheel....and i'll wait....and nothing happens! it just stays dead, then if I try to relaunch finder all the icons vanish and that's it....it won't come back up. then I have no finder, when I try to open something it tells me that Finder.app could not be launched. this is only ever fixed witha restart, only when I try to restart it closes everything and then sits there with an emoty screen other than the dock. I actually have to power the machine off to get it to to turn off.... ...what's happening?!
