A natural magnet for the craziest TKinter lovers out there

Hangs after maybe between 4 and 50 screen rewrites. sometimes CTRL C under Ubuntu starts it up again. Click go rewrites al the fonts the thing can find in a few windows.... Repeated.
TKinter has a cult following. I don''t really expect others to fix my problems, but you know, es since its a cult thing to love TCL ( or something .... ) Here is is.
Same on two different computers in Python 3.6 and 3.8
Plus I suppose you get to see for sure all your finest fonts as rendered in a real TK thing, not that this changes the worlds so much.
Thanks for the advice so far...
