Ubuntu 10.10, XTerm(261), Keyboard layout = Canadian

Somehow, the backquote (backtick = `) character can't be input does not get entered in XTerm. I type it and nothing happens. The cursor does not move forward.

I know it works because I can input it in Terminal (gnome-terminal). The only strange thing is that I have to type the key twice for it to appear.

Just to test it, I tried typing it in other applications, and the same thing happens. Have to type it twice in FF, gedit, etc. One more strange thing, I could not input it into this textbox in which I am typing this message. But I can input it in the URL bar, search bar, etc.

Someone please help me solve this mystery. I like to use XTerm and I need the backquotes.
