#1 Crash on Callback - Linux

[Jonathan Knapp]

when the NetworkConnection class makes a callback to the GUI it will sometimes crash. Only effects Linux and has a greater likelihood when the computer is under a heavier load.

possibly the result of a bug in python 2.7

It now works fine in linux and windows. It uses different callback methods for different platforms, this should be simplified so everything uses the same callback widget.
