>OK, I just found the article in MS acknowleging the bug. I really don't know what to do now. Any suggestion?
Shih,

Dump the wizard classes altogether and make your own. The wizard class hierarchy is poorly designed as it does early composition on the buttons and that causes all kinds of problem on subclassing.

Use the WizStyle class library as a place to get some ideas of how to write the code, but build your own class library. You can come here with questions as you do this to get ideas of how to put together the library.
