I am having a problem with my at sign (cant type it) and my question mark. I have repaired permissions but that did not help. It seems that my keyboard map is corrupted, is there a way to fix this
Do you have any haxies, system modifiers, or hot-key software installed (like QuicKeys)? Sometimes those programs muck with the keyboard, like the inability to type certain characters or letters.
I was unable to use the @ sign or the ? mark key, I turned off Shapeshifter a Haxie from Unsanity and as you can see they work now. I will contact Unsanity support.
