O$4 Set reference question

I have a window that has several instance variables of type list, or row.
Some of the subwindows need to access those lists or rows, so they include matching instance variables of type item ref, and a method:

Set reference iListA to $cwind.iListA.$ref

This works perfectly well.

The odd thing is that this code, following a breakpoint, sometimes reads:

Set reference iListA to $cwind.$ivars.21.$ref
or Set reference iListA to $cwind.$ivars.iListA.$ref

This does not appear to be harmful, but I wonder if there is a problem waiting for its chance to create havoc?
