how to make python socket server work with the app.MainLoop() in wxpython?

[zxo102]

Hi everyone,
    I am using a python socket server to collect data from a socket
client and then control a image location ( wxpython) with the data,
i.e. moving the image around in the wxpython frame.
   But  the "app.MainLoop()" in wxpython looks like conflicting with
the "while 1:" in socket server. After I commented the
"app.MainLoop()", everything is working except two things:
     1. if I click anywhere on the screen with the mouse, the image is
gong and only the empty frame( or panel) is left.
     2. if I don't  touch anything, the image is being moved around but
the previous images are left behind in the panel.
    I guess that may be caused by "app.MainLoop()" commented.
   Anybody knows how to make the two things work together? I really
appreciate your help.
   My sample code is modified based on the wxpython demo: image.py.
socket client is also attached for your reference.
