In essense, stage.focus retains a reference to the button when it is removed. Just added trace(stage.focus); to the end of each click handler in your example, and it would appear that this is one of the the differences between buttonMode=true/false. Unfortunately I don't have Flash Pro at work, so I won't be able to test this in the profiler until I get home tonight. Hey Josh,

I spent the last few days battling against this bug, I couldn't understand what I was doing wrong , I cleared all the references etc. but nothing the external SWF would not unload!!! Then after reading your post and setting buttonMode = false, everything worked fine. I commented on your bug report on JIRA and so did @alecmce and I'm surprised they set it as "Not a bug"..... we need some people at #Adobe that listen to us developers!!!!!!! :) Josh,

Documentation: <a href="http://help.adobe.com/en_US/AS3LCR/Flash_10.0/flash/system/System.html#gc()" rel="nofollow"><code>System.gc()</code></a>. It's meant to be used with the debugger version of Flash Player. I don't think it has any effect in the regular Flash Player that non-developers install. Thomas, yes, it calls the garbage collector.

System.gc();

Are you calling the Garbage Collector?

If a button has been clicked that had <code>buttonMode</code> set to <code>true</code>, it will not help to set it to <code>false</code> later. dim, I tried that.
