The problem with the Visual Basic Scrollbar is that it flashes. This is to indicate that it has focus. You can either set the Focus to something else on a form when the Scrollbar receives focus, or set the TabStop property to False:
Scrollbar.TabStop = False
You will need to have another control on the form. If there isn't one the scrollbar will continue to flash. A PictureBox is a good control for this because it can receive focus but has no visible indication of this.
