Thanks for the replies Larry and Mike. Mike, I have followed your code at http://econym.org.uk/gmap/tooltips4.htm and modified it to use my XML file. The results are at http://test.fs.cornell.edu/maps/ttSidebar_Test.htm
As you can see, the tooltips are not producing on rollover as they do in your example. Clicking on the marker or the item in the sidebar will open the balloon though.
