It seems like popupmanager doesn't work in Creative Suite SDK.
I can't use it manually and I can't use Alert. I get:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
Why? I thought popupmanager only handle "inwindow"-popups so I understand that a popup will not start a new window but shouldnt it work inside the plugin window?
It's a problem with the standard parent given when using popupmanager. (Application.application as parent doesn't work)
It works when I manually setting the parent to something else.
