Windows 7 is swallowing a keystroke combination

[laughingboy]

I'm using the gnu emacs editor under windows 7. I would like to bind a particular keystroke combination to an editor command. That combination is "control key" + ")", i.e., "control key" + "shift key" + "0".

However, it appears this keystroke combination is being swallowed by the OS somehow. The editor is not seeing the keystrokes, and I confirmed this behavior with KeyboardTest. Specifically, in KeyboardTest, I see the scan codes for control and shift, but while these are held down, I see no scan code for 0.

This happens even in safe mode. It works fine on Windows XP.

Anyone know of a way to diagnose / fix this?

Thanks,
Mike

My keyboard does the same thing. Might just be a design limitation.
