I know its long, did it in a hurry. I'll try and minimize once I'm back in the office. Thing is, it kinda has to be that deep to get the error; it should atleast be working except for the problem... as I did say, before making the library an object (referencing simplifer) it worked. Tring to use the previous call with slimply adding $self->ref did not work. Not using no strict refs. Full code has strict and warnings. I think the problem my be, in part, creating the threads.
