Popups are a special case. Panel/TitleWindow know when they've been popped up and resize themselves. You'll have to teach your Box to do the same.

I have a custom popup based on mx:Box. In it I have a dropdown. In this list dropdown you can select multiple items that once items are selected they stay in the dropdowns selected box (think multiselect combobo box). My custom pop has a width and height set to 300 by 300; Anyway, when I select several items the pop (not the dropdownlist) starts adding scrollbars when there are to many. If I set the horizontalscrollpolicy and verticallscrollpolicy to off then the pop start moving out of what looks like the popups viewablearea/scrollRect? So as the selecteditems in my dropdown gets longer the top of the popup start disappearing? Does the popupmanager need to know to increase its viewable area for the popup? Or is it possible to have a popup increase in size?
