TMS Diagram Studio Mouse Wheel Control

I am using TMS Diagram Component in my Apps.


I am using the following assignment:

Diagram.MouseWheelMode:= mwVertical;

I hoped that this would enable Mouse-wheel use in my diagram, but it has not. Is there some other property I need to change as well?

No, just that. Here it works fine, after setting MouseWheelMode to mwVertical, I can scroll the diagram vertically using mouse scroll.
