A friend has just pointed me to: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/72101/wo/oT= 5zorkeg3cH25IQOn622ueI85D/1.0.0.11.1.0.6.9.5.19.0.1.0.1.1.2.1.0.15 Maybe my powerbook is booting up with the bluetooth device in a=20 'compatability' keyboard/mouse mode to support that bluetooth keyboard, and= =20 it needs switched into 'normal' bluetooth mode somehow. ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
