Helen,

The server must serve the file as an appropriate content type.  It is  
currently served as text/plain.  You can use the curl command on unix  
(including Mac) systems to test this.

$ curl -I http://bioontology.org/projects/ontologies/radlex/ 
radlexOwlFulComponentl.owl
HTTP/1.1 200 OK
Date: Tue, 28 Aug 2007 21:08:02 GMT
Server: Apache/2.0.54 (Debian GNU/Linux) mod_jk/1.2.14 PHP/4.3.10-22  
proxy_html/2.4
Last-Modified: Fri, 20 Jul 2007 00:00:28 GMT
ETag: "8540fe-1cd0ee-9d5fff00"
Accept-Ranges: bytes
Content-Length: 1888494
Content-Type: text/plain

The content type for OWL in rdf/xml should be application/rdf+xml
This can be set in the mime.types file in the apache config.
Ask your friendly webmaster.

(The online version of the tabulator will peek and see whether a  
plain text file looks like RDF
but the extension version can't do this or on would never be able to  
serve the source of an RDF document up for the user to look at)
