After working around some silly browser bugs in Safari and other webkit based browsers I was able to coax Xanjax into compatibility with all major browsers. The webkit based browsers are unable to scroll content if the scrollbar is hidden. This is a massively stupid bug in a browser engine that lays claim to being the most compliant with W3C recommendations. It also has wierd behaviour on page redirection unlike all other browser engines. I certainly hope the developers address these bugs soon. For the moment, Xanjax degrades from event based navigation to polling; just for the buggy webkit browsers. If the developers either get around to fixing the problem in webkit, or providing an onhashchange event, Xanjax will just automatically use the best event model.
IE8 is a disappointment apart from the onhashchange event which is brilliant. The engine is seriously not much further toward meaningful W3C compliance than either IE6 or IE7.
Firefox and Opera browsers stand out because neither have bad habits from a web designers point of view. Congratulations to their design teams!
