You clicked an external link. This means you are leaving the Library of Lhankor Mhy to go somewhere else in the wild wide world, and we have no influence on what you see next. So we decline any responsibility as well.
Since the document you just read is very old, the links you find there are likely to have changed, gone, or even the complete website may have vanished. We prepared the following options for you:
Follow the link as is: http://www.parallelgraphics.com/products/cortona/ This was your original intention. On an error, it would be best to come here again to try the other link below.
You may be lucky to find the contents in the WayBackMachine of the internet Archive instead. This is useful, if the original changed content dramatically or vanished entirely.
The Web Archive to http://www.parallelgraphics.com/products/cortona/ You may find you need some self teaching to feel comfortable there, but it is worth-while.
