Flash IDE crashing when selecting a scene

There is a problem with the Flash development environment (CS3) when attempting to selecting one scene via the scene window. Flash crashes and an error message pops up saying ‘Flash CS3 has encountered a problem…send an error report to microsoft…etc’.

The same message apears if I attempt to publish the Flash application.

It maybe because this scene contains multiple videos (mp4, mp3, mswmm, wmv etc).

Is there a way to delete this scene as I am unable to select it in anyway via the Flash development environment?

thanks.
