Fixed! Here is the solution:
"Pressing the right shift key for 8 seconds in Word 2003is a short cut to FilterKeys. When you hit cancel though it changes the configuration of the keyboard. When you hit a letter key you will get capitals even though you did not engage the capital lock key. When you hit a number key you will get the symbol above that key as if you had hit the shift key with it.
To correct this problem and revert back to Words normal default mode
Press both SHIFT KEYS at the same time. This will cancel the change in the keyboard configuration.
To cancel the Shift Key short cut so that this problem does not occur again
* Hold down RIGHT SHIFT KEY for 8 seconds to bring up FilterKey popup
* Click on SETTINGS
* Under the Keyboard tab go to Filter Keys and click on SETTINGS
* Under Keyboard Shortcut click on the box USE SHORTCUT to remove check
mark
* Click OK
* At the bottom of the Accessibility Options box click APPLY then OK.
* Press both SHIFT KEYS to deactivate changes.
Keyboard should now return to normal mode and if you hold down shift key for 8 seconds or more you should never have this problem again."
