[Bug 953037] Re: "keydown" event changed?

[sanz]

** Description changed:

- 'onkeydown" perfectly before. "return false" will cancel the key
+ 'onkeydown" worked perfectly before. "return false" world cancel the key
  pressing action.
  
  after Ubuntu upgraded from 10.04 to 11.10, "return false" does not
  prevent the key stroke.
