Sitting here feeling dumb. My wife couldn't log onto the iMac, so I tried her password. No luck. I tried several combinations. No luck. I tried logging into my account. No luck. I told her our son might have done something to it, since he was the last person to successfully log on. I left it sitting idle and went off to do other things.
Fast forward several hours. I'm sitting here on my PC posting at MobileRead when two words suddenly jump into my head: CAPS LOCK.
