This appears to be a very severe result of a bug that was introduced into
Finder 6.0.  The Finder appears to no longer handles ICN#'s correctly.
For example, click once upon an application such as Lightspeed C that has
an icon that changes when you click on it.  (LC's icon changes from a
starfield to a box with a C inside of it)  Notice that the icon does not
correctly change.  (into the C in this case)  I believe that instead of
overlaying the mask with the original icon to get the new icon, the mask
is being drawn by itself.  This may be a change that Apple made to make
the use of the ICN# masks easier, so that instead of drawing an icon and
masking changes to it, you simply draw two seperate icons.
