[wxPython-users] Missed clicks with generic buttons on Mac OS 10.5

[Greg Benson]

Thanks Cody!

This works for me.  Furthermore, I made a similar change to wx/lib/ 
buttonpanel.py (see below) makes the buttons in the button panel  
responsive.  Perhaps this is a general issue of double click events  
being ignored in contexts where it should (or should be allowed to)  
only be interpreted as a mouse down event.

In System Preferences on my Mac, I adjusted my double click speed to  
the fastest setting.  This makes clicking fast on the TreeCtrl and  
TreeListCtrl more responsive, but this is not the best solution.
