To all you PC-using Mac people out there... A friend sent me the following email: "Can you please tell me why everytime I download a file it is doing it as a power point file? It is driving me nuts. KM" Only problem is, I haven't used a PC for years, and have no idea how to help him (I'm guessing it's something to do with MIME-types or something?) Anyway, I want to tell him to delete his Internet Explorer preferences, but don't know what the lingo is for PC-Users. Also, if I tell him to do the equivalent of deleting his preferences, what else is it going to do? Will it screw up his bookmarks? I was thinking of going onto a PC forum to ask this question, but I'm so out of my depth in that world that I thought I'd try here first.
