I had some problems installing Front Row with the Enabler software, and in the process of fixing it my fans went nutty so I had to reset the SMU. After this, the three volume keys and the eject keys stopped working (this is on an old black Apple keyboard). Some of the function keys weren't working on it anyway, so I got around to getting a brand new Apple Extended keyboard, but it has the same problem! I thought it might be that it isn't plugged in *directly* - I'm using the extension cable it comes with - but I have the same problem if I plug it straight in! Does anyone know what I can do to fix this? I'm using a 17" iMac G5 with 10.4.8, fully up-to-date.
