OK, I'll try to explain it better.
When I first start up the game -- with my CAPS LOCK key OFF -- the game plays normally like it's supposed to. That is, when I press W, my character walks. When I press W with the SHIFT key down, the character RUNS.
Now, if I want to run all the time, I press the CAPS LOCK key and I don't have to press SHIFT. (Still with me?

)
BUT, if my character gets killed and I restart from a saved game....while the CAPS LOCK key is still active....things REVERSE. And, deactivating the CAPS LOCK key doesn't change it for me. I have to actually exit the game, make sure my CAPS LOCK key is not active, then start the game again.
I need a way to revert to the 'default' settings while in the game. And, I've tried doing that by going to the OPTIONS/Controls and pressing the DEFAULT button. Doesn't work there, either.
It does get really annoying after a while.
