What steps will reproduce the problem? 1. Navigate to ScrollableMenu example (http://flexlib.googlecode.com/svn/trunk/examples/ScrollableMenus/ScrollableMenu _Sample.swf) 2. In Scrollable Menu panel, click Show Menu button. EXPECTED: max height of menu should be bounded by the bottom of the stage ACTUAL: Menu extends off the bottom of the stage and no scroll bars are displayed Control Version: current example on this site OS: MacOS 10.6.2 Browser 1: Firefox 3.5.6 Browser 2: Safar 4.04 Flash Player: MAC 10,0,32,18 (DEBUG)

WORKAROUND:  

Calculate the available space for the menu and set that value to the maxHeight

var point:Point = new Point();

//translate to global cooridates              
point = menuButton.localToGlobal(point);

//calculate maximum possible height, ignoring screen metrics
var maxPossibleListHeight:int = dataProvider.length * menu.rowHeight;

//calculate available space between the bottom of the button and the bottom of 
the stage
var stageAvailableHeightBelow:int = this.stage.height - point.y;

//if we don't have enough space below the button to display the desired number 
of rows
//explicitly set the max available height to force the menu to layout (and 
scroll) in
the available space
if( stageAvailableHeightBelow < maxPossibleListHeight )
    menu.maxHeight = stageAvailableHeightBelow;

menu.show(point.x, point.y);
