Team et al,
I have recently cleaned my KB by using a cloth while the computer was still on and somehow some of the buttons has switched.
When the question symbol (?) is used, I always get the number 8 or Asterisk (*) followed by the (?) symbol.
When the At symbol (@) is used, I always get the underscore symbol (_).
When the number (2) is used, I always get the minus symbol (-) either in front of the number or after.
This is not a windows language setting issue as I have never had such a setup configured.
