After you do that, you can change z-order of the button (bring to front) if necessary to get it on top of the wizard control.  You'll notice though, that the button has a little border around it that doesn't match the other buttons, that's because it belongs to the form, not the wizard control, so it's letting the forms back color show through.  You can fix this one of two ways: 1) add a panel that matches the back color of the footer of the WizardControl, make sure it's in the Form's Controls collection, and add your extra buttons to it or 2) change the back color of the Form to match the footer of the WizardControl.  The first option is probably best, because the second option will bleed through to all of the other controls that are marked as transparent, not just the button at the bottom.
