Why does a "Save" screw up the "scroll" settings?

[Kurt Kaufman]

I have also experienced strange goings-on (images whose position 
suddenly jumps way off screen, sudden appearance of images as gray 
rectangles, etc.), when I try to set up a window with scrolling 
contents, though I'm *not* sure that I'm doing it correctly.  I'd be 
interested in viewing the scripts of a project where this has been 
successfully implemented.  -That would reassure me greatly!
