TAVD Toolbar: How to avoid Hot Tracking of Image

Hi,
we use a TADV Toolbar Component (VCL Pack Version 10.6.9.0) in out application. The Images of the buttons are stored in a TVirtualImageList. How can I avoid that these Images are "doubled painted" at mouse hovering?

Mouse Hovers

I got it.

I simply had to set the property TAdvToolBarButton.Shaded to FALSE.
