Although I heard somewhere that that's more gimmick than guarantee,
and that it IS possible for an app to hook CAD - just that it's a lot
harder than building a simple window that looks like the login... but
it's pretty easy to fool a lot of people. Just look at the emails in
your spam box one day, find the ones spoofing a bank, and see what a
poor job they do. And yet they work.
