yes - I hadn't looked closely at scroll.c for a while, and was puzzling
over that part of it last night.  But I can see that it would do what 
you're describing.  (will investigate to see what improvement can be 
made).

yes - I didn't notice that (I see it's not updated for deleteCDKScrollItem 
either).  But that wouldn't explain the core dump (unless toggleSize is 
zero, and you are for instance using Sun's curses - I don't recall if it 
does any error checking for that case).
