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...

I ran your test program here and it generates 25 windows on my machine,
and I can click "run" at least half a dozen times. I tried closing the
font windows before clicking run again, and also just leaving the
windows up and generating many more windows. 300 windows. No hangs here
at all. Fedora 35 with Mate Desktop on X11 with compositing enabled.

It could be using up some system resource. tk could have some memory or

resource leak, possibly specific to the OP's machine. Try looking at
system memory with the system monitor as the program goes through its
paces. Maybe you will notice something suspicious.

there are no freezes, increase the number little by little. This may
give you some bounds on what's going on, or at least let your ultimate
program work by keeping the resource use under control.

Hello !

I seemed to have 'fixed it' by changing one line, really. I used:
# Do each thing
..for aWs in workWsL:
....aWs.update()
TO:
# Do each thing
..for aWs in workWsL:
....aWs.update_idletasks()

Thanks a lot ! This helps me visualise this is managed as a problem in a technical sense. I mean, there is always a requirement for real integration testing of all sorts for an attempt to release a program on a larger scale.
Now I know it works without stopping on 4 computers. Better then yesterday hugely.
Thank you.

Works through 20 presses of the "go" button on a Linux Mint VM. Because
of limited RAM allocated for the VM, after some iterations the program
slowed down because the VM had to start using swap memory. But there
did not seem to be any glitches or failures.
