Error when switching from Beta1 to Beta2

Hi,



I am seeing a new error since moving to flex sdk beta 2. This
happens when I launch a popUp using the popUp manager. The popup
itself is a TitleWindow with a single child of a flexlib
supertabNavigator (the problem persists if I switch to
tabNavigator). The tab navigator has a series of Forms as its
children. This is what I am seeing on
popUpManager.bringtofront(....)



Error: Error #1502: A script has executed for longer than the
default timeout period of 15 seconds.
