I actually posted something similar about 5 months ago. The same problem crops up when using such containers as a drop target; no background=no ability to detect drop. http://talsma.tv/post.cfm/using-vbox-as-a-drop-target
I think it is b/c there is "asset" to detect the mouse events. As soon as you add the background, there is something "physical" (or as physical as it gets in the programming world) that flash sees under the mouse. I know it is not a very satisfying explanation, but that is the way it is.
