We cannot guess, what's exactly going on, when you explain the purpose of the program. Of course, there are no bugs in the purpose, but in the implementation. Therefore we have to see the implementation to suggest an improvement. Please post the relevant part by editing the question, and not as comment or answer. Thanks.
