  It is not that unusual unfortunately.  And, here is an abbreviated
steps to take:

  - Turn off eToyFriendly preference.
  - open a workspace from the world menu.
  - Say, if you know the class of the graphical object, type:

    TheClassName allInstances

    and press Cmd-i to get the inspector.

  - Look toward the end of list (perhaps), and find one instance you
    think it should be reclaimed already.
  - Select the instance, and from the context-menu, and select perhaps
    "explore pointers" (or my favorite is "objects pointing to this
    value" as it is "leaner").
  - In the pointer explorer which shows the objects pointing to the
    graphical object, or the inspector, repeat the cycle to understand
    the graph of objects around it, and think which other object(s)
    is/are the root of cause.
