Thanks, that deals with the positional parameters nicely.

As for a patch... how about adding this to kaMap.initialize after 
dealing with the standard parameters:

    if (arguments.length > 3 && arguments[3] != '')
        szURL = szURL + sep + arguments[3];
        sep = "&";

If there is a fourth parameter, assume it is additional 
properly-formatted query parameters, so just tack it onto the end of the 
query string. Initialize can then be called with:

    myParams = 'myparam1=myvalue1&myparam2=myvalue2&...';
    myKaMap.initialize( map, extents, cps, myParams);

or just:

   myKaMap.initialize( map, extents, cps );

so existing code doesn't break.
