Hello and thanks for the answers.

@ Peter : I didn't found yet a buffer parameter like you said in MapServer.
The only thing I found for now is a OUTPUTFORMAT FORMATOPTION INTERLACE but
I really don't know if it's used for tilling, because MapServer help doesn't
give much informations about it.
I have to try...

@ Michele : here is the way I request :

-----------------------------------------------------------------------------------------------

		var mapOptions = {
				maxExtent: new OpenLayers.Bounds(minx, miny, maxx, maxy),
				maxResolution: "auto"
				};

		OpenLayers.IMAGE_RELOAD_ATTEMPTS = 3; 

		map = new OpenLayers.Map('map', mapOptions);

	    layer = new OpenLayers.Layer.MapServer("myMap", "url", {map:
'mapfile.map'});
        map.addLayers([layer]);

-----------------------------------------------------------------------------------------------

Making research on "Untiled mode", I found an example using parameter
"{singleTile: true}".
This parameter works well, my points and logos aren't cut anymore.
That's a solution I will keep for now, but if the map has a lot of
informations, loading one big tile could be time consuming.

I could make it more "user friendly" with a loading text for example.
Is there a "map loaded event" that I can use to display when the map is
loaded ?
Something like this :

-----------------------------------------------------------------------------------------------

		document.getElementById("loadingBox").innerHTML = "Loading map...";

        map.events.register('onloaded', map, function(evt) {
			document.getElementById("loadingBox").innerHTML = "";
		}
		
-----------------------------------------------------------------------------------------------

Where can I find all events available ?
I make my researchs on this site :
http://dev.openlayers.org/docs/files/OpenLayers-js.html
It seems pretty well, but when I look more deep inside, I realise it lacks
of details like objects' events.

Kind regards,
