Hi,
I tried to replicate this problem without success by using our WMS
server used during the OGC compliance tests. I also used the OGC test
suite requests. I joined both the map file and the requests sent (see
below). Theses requests contain three layers. In the first request,
the "Forest" layer is drawn first. In the second request, the "Forest"
layer is drawn last. You can also see that I modified the mapfile to
set the "Forest" layer status to "DEFAULT". It does not seem to affect
the drawing order. But maybe I'm missing something. Do we have access
your WMS server? It is possible to have a copy of your mapfile and the
request you are currently sending?

The requests used are.
