[Matplotlib-users] animation in thread

[Arash Azarmi]

main thread is owning the GUI. My Python installation runs Tkinter version
: 8.5 and this happens with Tkinter. I ran the same code on another machine
which used another GUI framework(not sure what was it) and it went well. So
I guess something is wrong with Tkinter.
