Yes, you can roll back to your previous version (I just did). If you Google "uninstall Internet Explorer 8", one of the hits is the MS page that tells you how. They have a tool that will do it for you, or you can follow the instructions and do it manually. If Matrix plans on releasing a further patch for PCK, they may want to look at this for compatibility. If a work-around emerges, I'll go back to IE 8, as I like the changes. I know Stridor tested Map Maker with IE 8 (worked for me too), but he didn't mention any of the other tools.
