Windows 10 plotting issue

[James0Hannam]

I'm having issues with the plot() command,and get the following error whenever I use it;

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:/msys64/home/LocalAdmin/auto/07p/python/auto/AUTOCommands.py", line 1848, in plot

    return self.tk.splitlist(self.tk.call(what))
_tkinter.TclError: bad window path name ".!toplevel.!frame.!frame.!frame2.!frame.!entry"

Should I be running python 2.7?
