I was in a pileup yesterday and little windows kept popping up on the screen of my 6400M, as if I was changing the bandwidth with the low shift. Except I was not touching anything but my paddles. Eventually the receive bandwidth was too small to use. I had to reload my profile to get it to stop and get things back like I wanted them. Any ideas why this happened? Is this a bug, or do I have some setting wrong? Or as Dr. Alfred Lanning once said, " There have always been ghosts in the machine. Random segments of code, that have grouped together to form unexpected protocols."
