Hi, I am new to volunteering at Bookshare. I am trying to proofread the training book Birds and Bees…. I have a MAC computer. When I download the book I am not able to see any color as mentioned in the manual i.e. reel one above section break, or blue green color of running headers. Do you have any suggestions as to what I might do to see the color of the print mentioned in the manual? Thanks for your help. Eric
