I reread the whole thread.
I really don't want to be annoying but :
With Scrollview2D, it works even when I implement a click event.
Your library is called XUIScrollView2D and the thread starts with "I develop the XUI version of the
ScrollView2D library that created @Informatix."
God save me, I expected similar
fundamental behavior.
Reread the whole ScrollView2D library, it will explain this topic.
