wx.EVT_MENU(self, idtool, self.OnExecute(idtool, e))

I changed it to this and it seems to be calling self.OnExecute befour
the editor comes up and then after the editor is up it doesn't respond
to anything.  I got rid off all the spaces but one in the text file (I
supose I need to use the strip method in real like though)..  I was
able to get an infinite loop by calling the editor as one of the
options and then it keeps calling itself.  It may be another problem
or perhaps I didn't grasp the answer.
