Thanks Sergey.

I am at the absolute beginners level, so please excuse my questions. I guess

they are pretty naive:)

Now, if I make these styles Normal - Bold - Underline what if the user

clicks both the btnBold and the btnUnderline, do I have to make a fourth

style "BoldAndUnderline"?

Regards,

Ole
