Like I said. We can help you when you provide an SSCCE. Talking in theory is fine, but it is a thousand times easier when we have some common working code to which we can refer. Plus that code...

I just counted 20 compiler errors in that code. Are you sure everything works how you think it does? Fix them and create an SSCCE that demonstrates what you're talking about, and we'll go from there.
