No dice, but thank you very much for taking the time to help, and I appreciate the pointer to Barry's document -- I much prefer to try and understand this stuff myself rather than simply following suggestions and not really knowing what is being done.

I think I am going to go ahead with the slowness of the volume up/down and see if it flies. If after a few weeks it's just not acceptable, I suppose there's no alternative to duplicating the entire activity in order to achieve what is needed.

Thanks again - bdc
