RE: addCDKScrollItem function in CDK

BTW, I didn't install any ncurses. Simply use whatever is with the OS, redHat9 or solaris8.

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).
