- Do you seriously expect us to inspect more than 1900 lines of code for you? Some very nice monks have tried to give you some clues as to what may be wrong, but most monks will simply not look at it. The constant advice here is to present the smallest possible piece of code that exhibits the problem. BTW, doing this exercise might help you very much finding the error by yourself. And I have no intention to look at your code, it is just too long (and, besides, it is a subject that I do not know very well, but even if it were one of my favorite topics, I would probably not take the time, I am willing to help, but I simply don't have the time and i expect some efforts from the OP to help those that are willing to help him or her).

- Using the <readmore> and </readmore> tags serves another purpose: make your post much faster to download. I am often reading PerlMonks from a mobile device on a mobile network while commuting between home and workplace, the connexion is not always great, and I get somewhat pis*ed off when the SOPW page takes ages to load because of a huge post. Especially if I have to load it each time I am getting back to the main SOPW page. I am sorry to insist, but it seems you did not get the message right, please do amend you post accordingly, do put your code section between <readmore> and </readmore> tags. That is going to make our lives easier.

Again, don't take this as an attack, this is not an attack, I am really trying to help you getting more helpful results.
