I upgraded to IE7 a while back and have been enjoying the improvements it has over 6. I still use Firefox as my main browser but it has been nice to use a decent browser when sites require IE. Things had been going swimmingly until all JavaScript quit working. Changing the security settings did not make a difference. After scouring the internet, I found the solution. Installing the latest Windows Scripting Update. I don't know why IE broke, I don't know why this fixes it...but hey, JavaScript works again!
