what invokeEvent()?
I can't seem to find any such function in DynAPI 3x
I'll simply use the ondragend of the scrollknob to invoke a function for now
(and onlclick of arrow, ect)
I understand there may be some issues with drag/click events..
Have these been clarified as of yet?
Are there changes in the api required?
