If you put an image into a file and choose it it will show you the dimensions in the corner. Occasionally when I resize this object by dragging it, the numbers will change. Occasionally they do not update. Why does this only happen occasionally? Is there a selection anywhere that will modify it so it shows it every time? Like if you accidentally make it too big and need to resize it again, the size could not appear while you carry it. Is this something that only features for images and not shapes?
