A quick question about Squeak's main window....

In the interest of creating a stand-alone Squeak-based application, I'd
like to have the main Squeak window be resized to the same size as my
main application Morph.

Is there a way to do this from within Squeak?  Right now I'm creating
an image and saving it with the window set to the "right size" manually.
This works, except on Windows where the window mysteriously shrinks
by several pixels in the vertical when re-started.

Thanks!
