Hi Dennis,
It is very difficult to understand the problem here.
1. Could you please explain what you mean when you say "it fails to function with regard to closing and opening front panels" ?
2. It may also help if you can attach your program so that I can take a look at it.
3. What is the program intended to do?? I mean, is it some sort of serial application etc.??
I hope to solve your problem soon.
Sincerely,
