OS 10.4.10 The number 6 doesn't work on the numeric keypad. works above the t and the y, but not over on the numeric keypad. Googled the problem, got an archive here, followed the directions, no luck. Created a new user, works fine under the new user. So the key works, just not under my user name. Followed these steps: First step, remove the contents of ~/Library/Caches/ and logout and log back in. Doesn't help? Second step, move ~/Library/Preferences/com.apple.Finder.plist to your Desktop, logout and log back in no luck. Weird, only one key, 6, doesn't register. Noticed while using Calculator but also doesn't work in other applications (Appleworks 6) Thanks.
