You are feeding it directly through? That's a bad idea...

Connect it up like this:

currently i have the top half of the daigram.

are you saying i should connect the [ - ] to the [ AN ] through a resistor? if so, what size resistor?

ps. why is it a bad idea?

Bad idea because you are leaving the AIN floating when it disconnects. When it floats, it slowly looses charge or keeps other AIN values' charge. You need a way to discharge it to ground.

Any resistor between like 1kohm and 100kohm is fine.

EDIT:

Think of it like this... The FB's analogue input channel is like a big bucket and holds charge with a small leak through the FB itself. You push the button, it charges the bucket for a little bit (like fills it up). Left by itself it slowly empties through the FB. But now you punch a huge hole in it. You push the button, and as long as it is pushed, the FB can read how much is going in. Release the button, the whole bucket gets dumped fast to ground.

thanks for your help so far ...

"can we (you) control windows master volume yet? "

i've searched through and although a few people have asked this question, it has never been answered.

sorry. nope not yet. After Vista came out I had to rethink it. Since I run Vista on my dev computer it becomes nearly impossible to make an XP only version and then work on the Vista/7 part later. I'll bump it up in priority

How do you mean? It's been a long time, I forget what I called things then.
