Using XP and Word 2003

I created several macros and set them up to run from the keyboard. They all have alt+ keyboard names, e.g. alt+2, alt+3, alt+m, etc.

Nothing drastic happen on the weekend to the computer that I know of. However, today my macros are not running from the keyboard.

If I open the macro tool, using Word, highlight the macro and click run, the macro will run. But, if I Key alt+2, the macro does not run. (Last week, it worked perfectly.)

I tried using the alt key on the right side of the keyboard and it still did not work.

Using my KVM switch, I switched to a different computer, and the macro keyboard functions on the different computer worked well, i.e., the problem is not with the keyboard, but rather with the computer.

I rebooted and it still does not work. I disconnected and reconnected the keyboard usb connector and it still does not work. I connected the keyboard directly to the computer, rather than through the KVM, and it still does not work.

Do you have any idea what the solution is to my problem?
