HyperCard’s windows are resizable: they can display an area as large as the current card, or as small as the smallest card size (64-by-64 pixels). You cannot make windows that are larger than the current card.
HyperCard’s windows don’t normally display their size boxes; command-shift-E makes the size box appear.
