We can't think of any clean way of doing this.  You might have batch files
that create dummy files as flags, but synchronization gets tricky on this
(if you crash VEE you can't run it again until you kill the flag file).

The lab guys say that a Maximized option is on the list.  We know about the
lack of position + geometry in Runtime and I think this one will be fixed
quickly ... not so sure about Maximized.
