Show us a minimal script that demonstrates the problem so we can reproduce it.

That is part of the problem... I tried a simplified example and I could not reproduce the problem. I know the issue is somewhere in my code. I know this is not the place for debugging many lines of code. So I thought it would be best to work this from the angle of what may cause this type of behavior? What would prevent a toplevel widget from minimizing? If I knew some causes, then I could look for those causes.

Thanks again.

Use the undo button in your editor to go back to just before the simplification step that made the problem go away then examine the code you were about to remove. The trick is to remove code that is unrelated to the problem until you have distilled the code down to a small sample that demonstrates the issue. Be warned, using this technique you may end up finding the solution yourself.

What would prevent a toplevel widget from minimizing?

For example, clicking a button triggers a callback (function).

Clicking minimize button, triggers a callback

The regular callback, changes the size of the window, it actually minimizes the toplevel window

Maybe you override this callback, with your own callback, which does not perform minimization
