A better way to deal with ambiguous selection would indeed be a 
significant improvement in usability.

Some questions:

* How does the user get to know that there is an ambiguity in the 
first place? Changed graphics of the mouse pointer? A remark in the 
status line? 

* How does the user know, which choice is the current one?

* What happens if the user ignores the possibility to cycle and just 
drags? 

* What is the geometric scope of the action? That is, how close do 
objects have to be to be included in the cycle?

* The HTML page mentions, the action does not work if rubberband move 
is enabled. What is the actual reason? Could this be overcome?
