Thank you for you reply.  Just one more question.  Doing what you suggest
was my first thought.  But I thought I read somewhere last night that using
"&" was not a good idea..... I have no idea why (it sounds good to me), but
I guess I just want to understand the difference between running it as a
"daemon" and just running it the background... if there is one.  Or maybe
someone has a URL with a good discussion on this someone could point me to.

Thanks.
