Question for Readers: Flex alignment with textarea controls

This post is more than 2 years old.

Here is an odd one for you. Consider the following Flex code:

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="" layout="vertical" horizontalAlign="left">
&lt;mx:VBox paddingLeft="10" paddingRight="10" width="80%"&gt;
	&lt;mx:Label text="First Label"  /&gt;
	&lt;mx:TextArea borderColor="#ff0000" borderThickness="3"/&gt;
	&lt;mx:Label text="Second Label" /&gt;



You would expect 3 items to show up, left aligned, in a VBox, and you get that of course, but the textarea is very slightly more to the left than the two labels. Check out this screen shot where I placed another window directly above the left edge of the text:

Notice the red border is very slightly smaller than the other ones. If I remove the borderColor and set borderThickness to 0, it is still there:

It almost seems as if Flex is aligning by the text of the TextArea control. In other words, when I typed in there it seemed as if that was the 'line' Flex used to line up all 3 controls, as opposed to the 'chrome' of the TextArea.

So am I seeing things, or is that what really is happening? And if so, is there where to align it by the chrome, not the text?
