[issue26673] Tkinter error when opening IDLE configuration menu (Tcl/Tk 8.6)

[Terry J. Reedy]

Terry J. Reedy added the comment:

Mark, changing the default font from Courier to TkFixedFont has introduced or exposed a bug in any of IDLE, tkinter, or tk 8.6.4 on Linux.  The result is that trying to open the configuration menu fails with TclError.  What do your think is the best solution?

Mathias, it seems to me that fontsize should alsways be an Intvar.  I have no idea why StringVar is used, except possibly as a workaround when the code was written.
