Adjusting projector to screen size

[Brian Koch]

I am new to director. I would like to create a projector that will scale my
movie to the size of the monitor.
My movie is 1024 x 768 and I'm working on a 800 x 600 monitor.
I consulted Technote #12609 and have assigned the following script exactly
as follows to a button sprite in my movie:

on mouseUp
myDrawRectFullScreen
end

on myDrawRectFullScreen
(the stage).rect = the desktopRectList[1]
(the stage).drawRect = the desktopRectList[1]
end

I then created a projector making sure I checked "In a window" option.
Still, no luck.
Can anyone tell me what I'm doing wrong?

Unlike vector graphics based Flash, Director doesn't scale bitmap
graphics on the fly that well, it always delivers the content at native
size. There is a loss in animation performance a vidual quality when
the program has the rescale bitmaps on the fly.

Usually one chooses the Fullscreen projector option that fills screen
area with stage background color.

It's possible to have lingo code scale sprits on the fly to adapt to a
screen size, it's probably only practicval for the moust simple
slideshow presentation using no score animation.,
