Printing a BookMorph page like a web page would be printed.

Thanks for this, I'll need a bit more time with it.

I meant a morph such as an ellipse embedded in the PasteUpMorph.

Probably both.

I was thinking of resizing through the all parts working in sync. Seems
that's not so simple. I have to learn more of the protocols.

So

this?

I have to look more at that. To be honest I don't like two way scrolls at
all. I'd prefer a trackball or joystick to maneuvre a large page and a
couple of buttons that could extend the width or height of a page. It would
make an odd book but.... What do you think of that idea, if there was a
trackball/joystick and buttons in the control panel ?

Well, I've since found that out. :-))
Thanks a lot.

When I can use my modem, zip, scanner and Squeak, I'll use it a lot more
than I do.  ;-)
