It seems to me that I should be able to do the following to detect a click event on a line on a google map:

var line = new GPolyline( ... );
map.addOverlay(line);
GEvent.addListener(line, "click", function(latlng){ alert("clicked"); });

The api reference says this is available in version 2.88, which was released in 2007(!?), so I'm assuming that's what I'm using, but I don't know how to confirm that.

I also tried setting the {clickable:true} option explicitly (it's supposed to be the default.) I've tested in FireFox 3 and Opera 9.6 so doubt it's browser specific. I'm also using jQuery on the page.

I have plenty of code detecting clicks on markers that works fine, clicking on lines would be really nice, can anyone enlighten me?
