I think this is a hardware issue, not software, sorry if I'm posting in the wrong place. (Edit - Sorry, realized too late that it is of course a software issue, but I don't know how to move my post...) I recently discovered the speech commands possibility on my PB G4, and have enjoyed trying things out. But it takes on a life of its own: When the PB is on, screen opened on my coffee table and I'm sitting quietly nearby reading a book, I will suddenly hear it say, "BACK!" or, "MAC FORUMS" or another bookmark in the bookmark bar of Safari - and the browser opens to that page. While surfing (quietly, no background noise) in Safari, the computer will suddenly yell out, "HOME!" or "BACK", and the page I'm looking at (or the bill I'm paying on nettbank ) is gone. I was half-way through a mail, and the computer said, "SEND!" and the mail whooshed out. I only turn on speech commands now to show people how it works, but I'd like to use it more often if only it would behave. Does this happen to anyone else, and how do you deal with it??
