Is there any reason why this line would cause swf file not to unload?
<s:VerticalLayout gap="0" horizontalAlign="justify" />
When i comment the layout from the skin the swf file unloads. But when it is present it does not unload.
No obvious reason. Compare memory snapshots with and without the layout.
That's the only difference? It should be harmless for the skin to reference
the systemManager. A reference going the other way would be a problem.
