The page has a panoramic image made up of six panes. When the mouse hovers over each of the panes it highlights the pane with a blue rectangle, and the click action links to a URL to show an enlarged version of the pane. In Safari/Webkit as well as the current version of Safari distributed in 10.4, when I put my mouse over any of the panes it always links to the fourth pane at this URL: http://www.fourmilab.ch/images/lignieres_alpes/figures/alpan_band_4.html This problem does not occur in Firefox on the Mac, and on the PC Opera 9.1, Firefox 2, or IE 6 and 7.
At a first glance, the problem seems to be caused by this code having no effect: document.getElementById("panlink").pathname = document.getElementById("panlink").pathname.replace(/_band_\d/, "_band_" + where);
I am unable to reproduce this bug using Mac nightly r86007.
