The topLeft property returns or sets a point equal to items 1 and 2 of an element’s rectangle. If you set the topLeft of an object, it moves; the object's size remains the same. You can’t set the topLeft of cards: use the rect, height, and width properties to resize the cards in a stack. You can’t set the topLeft of the menu bar. HyperCard determines the topLeft of buttons, fields, and HyperCard’s built-in windows relative to the top-left corner of the current card. HyperCard determines the topLeft of the card window relative to the top-left corner of the screen with the menu bar.
