Win32/MFC dialog layouts are based off absolute positioning of all widgets, with a few concessions to resizability (like the ability to select whether a widget moves down or stay still when a window gets taller). This is the reason why many dialogs, like Run, or Windows Explorer file properties, cannot be resized.

Any hierarchy (group boxes holding widgets) is purely visual, and the rectangle doesn't "own" its child widgets in a programmatic sense.

Text widgets have a fixed size. If your font gets wider (from DPI scaling or translations), text can become cut off or overflow onto the next line and disappear.
