[h-e-w] Python mode and graphics

[David Einstein]

When running either wxPython or tkInter programs from the emacs inferior python mode, either the programs do not show up on the screen (wxPython), or the inferior Python mode becomes unresponsive (tkInter).  This happens only on MsWindows, It works on OSX and Linux, but fails on two different XP machines.  I suspect that there is some extra flag that needs to be passed to the inferior python process, but I have no clue what it should be.
Thanks,
