One quick thought that I have since you say that a layer image is blurred on the bottom portion is that you have FORMATOPTION INTERLACE=ON set. This turns on interlacing and sometimes I see that it takes a few seconds on my mapserver to fully render the image. If you want to prevent this blurring turn that setting off in your Mapfile.

I am having a problem and it is beginning to look like mapserver is behind it somehow. I am using ms4w 2.2.6 to render postgres data to openlayers. Mapserver is configured to use IIS\CGI instead of apache. I am actually having 2 problems, but I am not sure that they are not related. One problem is that sometimes the server just isn't returning any data for different layers to OpenLayers. I have talked extensively with the OL guys and have come back to the fact that if I take the URL that is requesting the information from mapserver, then I get: "The specified CGI application misbehaved by not returning a complete set of HTTP headers." The most consistent way I can reproduce this is to zoom in real close. The second problem I am having is that when I am getting layer images back, they are blurred on the bottom portion. It looks like someone took a cloth and just wiped a whiteboard. I am about 5 days late on a deadline to have this up and running, so I am open to try any suggestions that someone may have. Thanks in advance, Lee
