I am running Geny v-1.31 from Debian Stretch on my Linux platform.

FOr unknown reasons I have started getting error messages from a Python 3..5 script I wrote to plot multiple curves frlom data generated by a FORTRAN09 program.

Enter Molecule ID: A
Traceback (most recent call last):
  File "MolT_5IMT_w_3_2_plot.py", line 83, in <module>
    fig.savefig(name_plt,bbox_inches='tight')

    return self.tk.call('wm', 'geometry', self._w, newGeometry)
_tkinter.TclError: can't invoke "wm" command: application has been destroyed

Press return to continue

Unfortunately, I am an Organic Chemist and not really a Python programmer and wpuld really appreciate some help in solving this problem.

Thanks in advance.
