I think that if instead of running the manual directly from the CD, you used my Index, you would find it works much better.
You can download the Index here:

Once downloaded and unzipped, follow the direction in the ReadMe file and copy the contents of the CD on to your hard drive. Using my Index will result in getting to what you want in the manual much quicker, and simpler.
Let me know if you have any problems.
