Hi - I'm new here and I'm having some keyboard issues that I can't believe I haven't been able to fix on my own yet. Hope someone out there can help! I'm working with on a little older iMac - running 10.4.11 - Intel. 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. Anybody have any thoughts? Thank you!
