I have Acrobat Javascript disabled in Reader 9.3.2 as a security measure, but I know how to change that setting rather easily if I had a need to do that. As I recall, there were severe security issues related to Javascript in Acrobat Reader which is why I have it disabled. Also, as I recall, Reader 8 was riddled with security flaws as well. I'm not sure that you'd want to open up a can of worms for your end users.
