Save the result and open it up in a notepad.  The text of the return  
may indicate where the problem is. The whole "download" issue is a  
side-effect of the OGC decision to specify their own MIME-types (why?  
why?! why?!!) for the XML error returns in WMS (instead of just using  
text/xml like good puppies).  Your browser sees a MIME-type it  
doesn't understand, cannot find a handler for it, and falls back on  
the only remaining option, save it to disk.  But it's just a text XML  
chunk, I bet, and if your lucky it even describes your error  
condition in a helpful way.
