SplitterWindow OnDoubleClickSash problem

[Larry Bates]

class MySplitterWindow(wx.SplitterWindow):
     def OnDoubleClickSash(self, event):
         print "OnDoubleClickSash event"
         #
         # I want to disable this, but somehow it gets done anyway even though
         # I don't call event.Skip() ????
         #
         return

in my Frame I have bound the EVT_SPLITTER_DCLICK to this method

When I run this the print statement executes, but the sash bar is delete even 
though I didn't call event.Skip().  I thought I could trap this and disable 
double-clicking on the sash this way.  Am I missing something?

Thanks in advance for your assistance.
