[python-win32] Issues with tkinter, COM servers and Python 3.x

[Diego Vélez Torres]

Hi Tim:

I just fixed the issue by applying your advise. But (...and here comes a
big BUT !!!), why do I have to do this when calling tkinter inside a COM
server, meanwhile this is not necessarily when outside a COM?  If my COM
Server were using tkinter directly I could rely on this trick.  However, my
originally problem came up by trying to use pyplot from Matplotlib.  I
found that pyplot.figure()  launches a tk instance.  Therefore, in order to
use this library (and any other that uses tkinter) within COMs, I must
modify the source codes.  It doesn't seem this to be a feasible solution.
Is there any other solution?

Best regards,
