Ya, I understand Steve ...but it marches by that; rather than chiming again the desktop opens as usual. If I keep the keys down - I get like a bell ringing telling me to Let Up Dude! ...I never get the second, or more, chime.
One of my HD suppliers FAQ's said to Cmd+Opt+O+F (I also tried Zero..) to open a command line to reset to the defaults, but that does not work either - desktop opens as usual. I'm on a new Alum. mac keyboard via USB. Confusing...?!
