[flexcoders] Using Effects with TitleWindow show/hide?

[Danko Kozar]

Is it possible to use mx:Effects with TitleWindow popped up by 
PopUpManager? 
I'd like to use some Move and Resize effects on window show and hide - 
just to make it slide in and out.
I've try it using showEffect and hideEffect property of TitleWindow, 
but it doesn't work.
