It was my suspicion that the Qt::CustomizeWindowHint flag needed to be added everywhere the default was being overridden. I'm not ready to blame Qt6.10.x yet. The first of these custom window flags were added only 3 weeks ago. I suspect the same thing would have happened had we used them in conjunction with Qt6.9.3. I probably never would have noticed new min/max buttons on dialogs unless someone had said something.

I still don't think we need to blunt-force the About box (and every other modal dialog that now has min/max buttons). I think we just need to properly add the Qt::CustomizeWindowHint flag to all three of the original places we added the new code. Every place I've looked said that flag needs to used when customizing the buttons you want to appear on dialogs. And we currently are not using it.
