Solve : How to change a weird cursor (input field) back to normal?

1.	Solve : How to change a weird cursor (input field) back to normal?
Answer» I am BUSY fixing an XP system for someone else. All has succeeded without too many problems except for the cursor in input fields. This has BECOME a large block covering more than ONE position and I cannot GET it BACK to the normal thin line. Obviously, I tried "start-control panel -mouse -pointers", but the input field cursor is not in that list. Anybody?
