In DialogRRHH() you create a new application object with a new event 
loop, while you already have one running. wxPython should have only one 
application object though; otherwise there conflicts between the 
different event loops. Also you don't need to call 
wx.InitAllImageHandlers() again.

It seems to me that in DialogRRHH() you want to create a dialog and wait 
until the user closes it. In that case, it should look more or less like 
this (beware, I'm not a wxPython expert myself):

     def DialogRRHH(self, event):
         DialogRRHH = MTRRHH(None, -1, "")
         DialogRRHH.ShowModal()

Also, in that case MTRRHH should be a wxDialog, not a wxFrame.

In case you want to show MTRRHH without waiting for the user to close 
it, use DialogRRHH.Show() instead of .ShowModal(). I think MTRRHH can be 
either a wxDialog or a wxForm in that case.
