Windows quick Keys.

I'm going to be honest. I'm trying to use a GBA Emulator. Now I'm not going to be honest. I have ALL the games I play on my emulator, on cartridge.

But enough Details. Whenever I use this emulator, (it runs in a standard windows app window, like persay IE, Firefox, etc.) but the problem is those little menu quick-keys to quickly access the menu. Example: Ctrl+X Will close the application, ctrl+C will open the CHEATs menu.
I'm wondering if theres a way to disable all the menu quick-keys so when I go to execute that killer move that involves me to push 2 or more buttons, I don't accidentally push Ctrl+X and have to restart the entire thing.

Oh, I'm also using Windows XP Professional SP 2
