As I've said you shouldn't take my examples as correct because I almost
never fiddle with stickiness.  So have you checked that it does what it is
supposed to do: I.e. insert a char at position 11 and another at position
6 and make sure that only the one at position 11 is visible.  As long as the
char inserted at position 11 is invisible or if the char inserted at
position 6 is visible, Emacs will feel compelled to accept 6 as
a legitimately desirable position.

I think you first have to understand that if your program doesn't accept
6 as an answer here, it's got a problem.  Have you tried again to move in
various directions in Emacs-21.3?  Has it always moved to 11?  If so, tell
me precisely what you tried, because you must have missed one case.
