I recall a lecturer saying in his introductory remarks: "For every equation used in a lecture half the audience is lost". So it is with lines of code. Most of us help out around here to learn and to return. However we have limited resources available and there are many few monks interested in reading through 300 lines of code than there are interested in reading through 30 lines of code. So, sure post 300 lines of code. Maybe someone will look at it for you.

There are at least two benefits to you in reducing the sizeofthe code demonstrating the problem: you are more likely to get someone interested in looking at it, and you learn a lot more about the actual issue yourself. In fact you are likely to learn so much about it that you solve your own problem. That isn't actually a bad out come. ;)
