Thanks for letting us know what happened (& that LW is working ok otherwise.) I bought a wireless keyboard & mouse with my mac, I use neither, I dislike them. The bluetooth card on my mac might be buggy. I've read many reports about similar issues with continually losing connection with mouse or keyboard. Wired is safe for me.

Black keyboard, does not sound like a mac brand. Sounds like a 3rd party one.

I want to get a new keyboard, but Mac online are fast to remove older models, the newer one designed for use with Lion. I don't need all that connect online stuff or whiz bang F key options. I like what I have, don't wish to lose those button abilities for sound, monitor & disk tray or hide all to show desktop. I spilt water on my keyboard some days back, now my control & shift-lock keys don't work, just as well my keyboard has dual keys for control.
