Hi, I have a huge problem in when working in Word 2003.

Let's say I open a new document and type these 3 lines:


My name is Tony
I am 25 years old
My car is black


Then I select the line "I am 25 years old" and want to make it bold. Well all my text will become bold.

This is for a 3 lines text is not a big problem to rectify, but with a 20+ pages documents it does that everytime I want to make text centered, bold, underlined.. etc etc.

Why does it change all the text and not only what I selected?

Thanks for helping.
