Something happened recently with my laptop (I don't know what, I can't recall anything I did that can cause something like this) and now I'm unable to type ampersand (&). And not just in a particular application it looks like a system wide problem.
The key works on it's own (c) and AltGr works with other keys too. The combination doesn't seem like a shortcut, it doesn't do anything. What can possibly cause this? (I'm using Windows XP SP3)
EDIT: the keyboard is Hungarian, Windows seems to use it like a Hungarian keyboard and I can type everything except the ampersand.
