mouse scrool wheel events

Hello!

I noted that in CVI 9.0 when  using a slide control (hot mode) with the mouse scroll wheel, the only event generated is EVENT_MOUSE_WHEEL_SCROLL.

But in CVI 2013 the same control generates EVENT_MOUSE_WHEEL_SCROLL, EVENT_VAL_CHANGED and EVENT_COMMIT.

Is this behavior correct?

Thanks in advance.
