Thanks; it was not obvious to me that the second problem was also seen in the
OpenLayers application. The image on the OpenLayers discussion seems to
indicate a MapServer crash or other failure, as you've already suggested there.<br>
<br>
Lee, I think you should ignore the "blurry" problem for now and focus
exclusively on:<br>
<br>
" 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." "<br>
<br>
You seem to be building on quicksand, and if you don't fix the foundation
there's no point in trying to figure out why the pictures on the walls don't
hang straight.<br>
<br>
If you can post details about the URL and the error we might be able to try to
help debug. Looking for debug and Web server logs can also be helpful to
understand why the CGI failed, as is running mapserv from the command line.<br>

> INTERLACE=ON is not "wrong". Tim is pointing out that if
you're viewing an interlaced output image, the first, alternating set of
scanlines will be displayed and then your browser will start again at the top
of the image, filling in the alternate interlacing lines. This will cause
the top of the image to appear complete while the bottom is "blurry".
You can see variations on these visual artifacts depending on your browser, and
the effect is more pronounced over a slow connection.<br>

<br>
Note that this will almost never be the case with OpenLayers because<br>
OpenLayers hides images until they are completely loaded (for technical<br>
reasons unrelated to this), so if someone reports this behavior in<br>
OpenLayers, you can usually be sure it's not an interlacing thing.<br>
