I realized that the HDividedBox and VDividedBox components sometimes hang when I mouseover the divider. Upon investigation, found out that a new method was added in Flex 3 beta 3 in UIComponent.as for get cursorManager which has a while loop. If you have the HDividedBox in a deep nested component, the while loop takes forever and the application even hangs for a brief interval before the divided cursor shows up. Has anyone else noticed this problem?
