Maybe it's just MacIntosh computers (Macs) or maybe it's other computers, too. I don't often use PCs so I can't judge. Sometimes I hit the back space and I get a message that says something to the effect of  "Are you sure you want to do this? If so another form will have to be sent." It almost makes me feel guilty, like I am inconveniencing someone. Surely a personal computer hasn't become that personal that  it takes it personally when I back space to a previous page. Anybody else have a comment on this (or the other blogs).
