Hi - I posted this about a month ago in the iMac forum and it hasn't been resolved. Someone suggested I move it over to this forum - so here goes. My right shift key, arrow up key, and the 4, 5, and 6 keys on the number pad are all not working. Nothing has spilled. I've plugged in a different keyboard - same problem. Zapped pram - problem remains. Trashed prefs, restarted, repaired disk permissions, mouse keys off, checked international settings, speech setting off - everything I could find online - nothing has worked. The keyboard viewer is showing that the keys are not being seen. Two things have changed since I originally posted this in the iMac forum. I upgraded from 10.4 to 10.6 (finally), but the problem remains. I've also tried out my wireless keyboard that I use with my laptop. Strangely - the wireless works fine. Anybody have any thoughts? Why would TWO usb connected keyboards have the exact same issues, and the wireless work fine? I'm fine with just buying a new keyboard - but I'm concerned that the same problem will happen with a new one. Any thoughts are welcome. Thank you!
