minHeight and minWidth are usually used in conjunction with percentage-based height and width. When the content becomes too small to view, the min values kick in. This isn't a bug. It just depends on how you set-up your view. If you set the minHeight/Width of the canvas to an explicit value and the canvas' container (HDividedBox) has scroll polices = "false", the parent container acts like a mask; the scrollBars will not be visible or accessible because the underlying canvas extends beyon the parent's dimensions. Does this make sense? Since you explicitly defined the size of the text area, it will never get smaller than the set height and width dimensions. Your choice here is whether to show scrollBars up the displayList or not. It's actually quite logical. It just takes some forethought to apply correctly. I learned a couple of things from answering your question. Especially the clipContent="false" behavior. Thanks.
