ComboBoxes draw their dropdowns on the _root. If you lock the root in a nested clip, they'll draw their dropdowns there. This is why you're getting z-index problems.
Second, if you're having an issue where _height is not returning the true _height, then store the original height in a variable and use that. Here is some pseudocode: var originalHeight:Number = _height; function getCurrentHeight():Number { if (_height > originalHeight && myComboBoxIsClosed) { return originalHeight; } else { return _height; } } HTH, Steven _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
