Perhaps, but you have to be careful with the StateImages property.  State
images have additional special processing on them, both by the ListView and
the OS in general.  This is because state indexes are not true absolute
indexes in the ImageList.  Firstly, they are 1-based, not 0-based.
Secondly, they are actually masked with other values, and as such they need
to be translated back to indexes when needed.  In fact, now that I think
about it, that's probably why your images are getting messed up
periodically, since you've swapped the ImageLists so the ListView/OS is
probably ending up doing its extra processing on the wrong list.  That would
probably produce the incorrect indexes you are seeing.

Honestly, I don't think you're going to be able to do what you're trying to
do, at least not by using the native behaviors.  ListView controls simply
weren't designed to properly handle everything you're tying to throw at it
at once.  You really should swap your ImageLists, but then you lose your
header images.  Leave the ImageLists as they are so the header images work,
and you mess up your image indexes.  You may have to simply disable the
ListView's native header and use a separate THeaderControl instead.  Then
you can give the THeaderControl its own separate ImageList.  But then you
have the new chore of keeping the two components in sync with each other if
the user resizes columns as such.  Its a win-lose situation anyway you look
at it.
