Never getting EVT_SCROLLWIN events

Hi list,
I have a ScrolledWindow and I’m listening to its EVT_SCROLLWIN events from different classes: itself, its parent and an external class. NONE of said classes are getting their handlers called. My only guess is that something else is processing the scrolling events so that my handlers are never getting it.

The scrolling itself happens correctly, so someone must be processing and not Skip()ing the event. Is there a way to know who processes the event without skipping it?

Thanks,

Leo
