<div>Frank,</div>
<div>thanks for your answer, actually I'm moving this "my-first-MapServer" to a public host, in order to test it and then make it accessible to a (some) possible end-user(s). Query on classified rasters was the last thing to fix, so, as it can't be fixed now, I hope to put everything online in few days, with contents of mapfile and templates accessible to visitors.

<div>Besides this, tell me what else should I do to let you reproduce the same problem.</div>
<div> </div>
<div>... and thanks again!</div>
