Hiding another process in Mac OS 9 and 10

[Jack Rarick]

I have written a Metacard app that at some point needs to launch an
Applescript app that uses QuickTime Pro to convert some digital and analog
video to other formats.  Question:  Does anyone know of a way to keep the
Applescript app working in the background so that it cannot be seen?
(Actually, so the QT player can't be seen.) I don't have any problem
figuring out when it is done working and when the Metacard script should
continue .. I just don't want the user to see screens flying around etc.

Thanks in advance,
