What is your operating system?  Reader version?

Does the document contain actual text, or is it just a scanned image?

My operating system is windows 8 and the reader version is adobe reader XI.

The documents are scanned images. But I thought I could highlight and

comment on other scanned images. Maybe they have different settings?
