Anyone else having an issue with Lion and your keyboard where keys just stop working? I randomly lose I and L. I don't believe this is hardware related because I can sometimes switch applications and it comes back. I've read about this bug on Apple support forums but all of the fixes have not worked. What I've done so far; reinstalled (not clean) deleted entire /Library/Preferences deleted various plists from user Library, com.apple.dock.plist, com.apple.systempreferences.plist, com.apple.symbolichotkeys.plist.. others that I can't remember I've turned key repeat back to the default setting (off). I have noticed I sometimes can switch to Terminal, type the letter and it fixes itself. Bug reports I've read point to Mission Control but I do not use it at all and have all key shortcuts to it turned off. Launchpad has made this happen three times in a row.. and magically it will start working again sometimes without switching applications. It's still randomly happening and happened four times in the time just to type this post. I am about five seconds away from giving this machine the old yeller treatment out of frustration.
