V-scroll event problem in ActiveX GUI (General questions)

by madkoala, (5570 days ago)

I'm working on an Instant messenger using your component and it works well.
But I have a problem.

I created a roster tree with wodXMPP activex GUI and
mouse wheel does not work on it!!

When I move mouse wheel on the component, it doesn't react.
I only can use vertical scroll bar, which is very uncomportable.

Would you let me know how to enable mouse wheel scroll event?
Thanks in advance.
