Navigate to the page in the URL, and press the "Render" button in the demo. Then navigate to the radio buttons governing selection of "Wines" using TAB, and use the arrow cursor keys to update the selection. No "onchange" event is received for this control, as shown by the failure of the update in the right-hand pane. Operate the radio buttons using the mouse - the "wineList: choice:" entry will update indicating that onchange is received. This demo works in every recent browser which is not based on WebKit of 528+ (IE 6+/Firefox 2+/Opera 9+). This has been tested on the latest Safari release on Mac and Windows, as well as on the latest Webkit nightly (at time of writing, r52746 of SVN). At the moment, the only workaround is to manually detect the delivered event via "onkeyup". This issue is a significant impediment to delivery of accessible applications on the WebKit platform.
