Bump. No one has seen this?
Dear Gregory Lafrance ,
Did you solved the above problem.
I am also facing the same problem. If you solved the above problem pl help me.
Can you please provide a sample application?
If you override the height of the internal textInput to be the height of the combobox, it fixes the issue. Create another class that overrides mx:ComboBox and add the following.
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
// Force the text box to the unscaled height so that the bottom of letters like 'g' don't get cut off.
textInput.height = unscaledHeight;
