<div>Hello,</div>
<div> </div>
<div>I received a report that a GeoMOOSE / Mapserver web mapping application <a href="http://geomoose.lyonco.org/MurrayMoose/"><font color="blue"><u>http://geomoose.lyonco.org/MurrayMoose/</u></font></a> is creating pink tiles when zoomed out. I found out
that the user has a very large monitor, so I thought that I may have forgot to set the MAP MAXSIZE parameter. That was not the issue.</div>
<div> </div>
<div>Next, The user then reported that the pink screen only was present when boundary>municipal layer was turned on. This particular layer is part of a mapfile that contains several layers. All of the other layers are working fine. Also when he zooms into
the map the layer appears on his application as expected. So I thought that the issue has to be with the layers* within the mapfile.</div>
<div> </div>
<div>*The municipal boundary layer in GeoMOOSE is tied to the Townships and CityLimits layer in a single map file.</div>
<div> </div>
<div>The layer file itself is a generic template that I have been using for several different applications without complaint. I also tested the application on my computer using a variety of browsers including IE8, which is the browser the user reported that
he was having trouble with the pink screens. I also adjusted the browser size to make it the requested image larger, zoomed in and out, and I have not had any trouble.</div>
<div> </div>
<div>I included a part of my map file as well as a log file from what I think is a unsuccessful request and a successful request from the same user.</div>
