To clarify recent comments on the Nisus upgrade, there are two versions, 3.4L and 3.4C, which differ in two ways. The most common version, Nisus 3.4L, supports Roman languages and Japanese, and is NOT copy protected. Nisus 3.4C adds support for all non-Roman languages (Farsi, Russian, Hebrew, Arabic, etc.) and is copy protected with a dongle. I won't discuss this issue further, but I'm sure Nisus Software would gladly listen to constructive suggestions on how they can avoid the dongle and still convince recalcitrant overseas distributors to carry Nisus 3.4C.
