#
# o It appears that wx.Timer has an issue where if you use
#
#       self.timer = wx.Timer(self, -1)
#
#   to create it, then
#
#       self.timer.GetId()
#
#   doesn't seem to return anything meaningful. In the demo, doing this
#   results in only one of the two handlers being called for both timers.
#   This means that
#
#       self.Bind(wx.EVT_TIMER, self.onTimer, self.timer)
#
#   doesn't work right. However, using
#
#       self.timer = wx.Timer(self, wx.NewId())
#
#   makes it work OK. I believe this is a bug, but wiser heads than mine
#   should determine this.
