 <p>I have found that the issue lies with the references to icon files and an older version of the jquery library being used. I'm still not sure why it wasn't an issue for IE, but was for chrome. </p> <p>My theory on why the incorrect reference to the icon file was causing a problem was that when no icons were rendered on the Dynatree object, Chrome did not insert any "pixel address" on which to click. I realize that is not the correct term, but it is my theory. In IE, it did not seem to be a problem.</p> <p>When I rendered the page after correcting the reference to the icon file, all worked as expected.</p>
