I discovered after the close of Apple's support last night that the Ambient Light Sensor isn't being recognized on my Powerbook. So far the "longer than 15 minutes" that I was to be on hold definately has been longer than 15 minutes. It wouldn't be so bad if the hold music wasn't so bad and if there wasn't an interruption every 20 seconds telling me to continue to hold making any attempt to listen to the music a problem as well. URG! Evidently they need to crank up thier Blue Pumpkin and get some folks scheduled.
It's now 1.5 hours since I called. I'm on hold with a product specailist. Either they think I'm blowing smoke or they seem to think it has something to do with Panther. As far as I know the keyboard has never had backlight function. However, there is a report on Macintouch today that someone else whose keyboard DID work under 10.2 with the problem on 10.3.
