While at Tech Ed Australia, Richard caught up with Chris Jackson to talk about the latest problem in application compatibility - web applications dependent on IE6. When released ten years ago, IE6 was a paragon of web standards, but the world has moved on and now IE6 is a pariah. Chris talks about how web applications dependent on IE6 are actually blocking XP to Windows 7 upgrades, but that ultimately the reason to move your applications off IE6 is a web standards issue.
