Looks like I have a question after all, how do you justify missing out a simple and yet quite essential point within the "how to" section of installing the relevant software? How do you expect us to know that bizarrely, entering your registration code followed by pressin the tab key, of which takes you back to the name section of the dialogue box completes the registration?
I've wasted time doing this, and if anything this process has been anything but, quick time... see what I did there?
1) This is a user-to-user forum. If you have feedback comments for Apple, then use the product feedback form to make them known. You are preaching to choir here.
2) Had you
a) read the "How To" instrunctions targeting Snow Leoppard and Lion Operating Systems rather than the instructions for the Leopard OS,
b) posted your question here as soon as you discovered your problem, or
c) been more familiar with the work flows that pre-date QT 7 "System Preference" registration work flows,
then you would probably not have wasted so much of your time in unproductive activities.
