This is pretty cool. It also means that you can add a property to store an object reference that will persist through a RELEASE ALL. I can

_SCREEN.AddProperty('oShell',CREATEOBJECT('Shell.Application'))
release all && ain't no thang
_Screen.Shell.Open('mailto:esmoore@flash.net')

_screen.Shell persists as a way to use Shellexecute with one line.
