Cannot intercept a double-click

I am testing the demo in Delphi, but cannot intercept the double-click event.

I assumed that since I can set the OnMouseDown property, that the double-click event would be accessible. My logic works for an ordinary windowed component, but not for a TWPViewPDF component.

I've searched the user manual and the forums, but found no information regarding why this does not work.

On of the primary reasons I'm evaluating this product is because I need this ability.

Is there some configuration option I've overlooked?

Thanks for any help you can give.
