Supported Web Browsers & Platforms

Users expect, quite reasonably, to be able to view a website in their preferred browser, regardless of whether they are using the Mac, Windows or Linux operating systems. Although this web application conforms rigorously to web standards, when initially launched in 2011 there was a Javascript problem, unique to Microsoft Internet Explorer, that affected the pathway maps. We do not know whether this is still present in more recent versions of Internet Explorer, but if it is and you want the maps we are afraid that you will have to use another browser: Firefox, Safari, Chrome or Opera all work. (It should be evident from the foregoing that you also need JavaScript enabled in your browser.)
