Description

<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="955" height="600"
rollOut="trace('app roll out')">

<s:Button id="left" width="100" height="100%"/>
<s:Button id="center" left="100" right="100" height="100%" rollOver="trace('center over');"/>
<s:Button id="right" right="0" width="100" height="100%"/>

</s:Application>

Actual Results:
Clicking the Left button traces 'app roll out'
Clicking the Right button traces 'center over'

Expected Results:
Clicking either button shouldn't fire a rollOver for Center or a rollOut for the Application.

Workaround (if any):
I couldn't find one. I tried different layout schemes, fixed widths, and MX components to no avail.

I was able to reproduce this bug on two different computers each running:
Mac OSX 10.5
Firefox 3.6
Flash Player 10.0.45.2

Other browsers did not show this problem.
