John, ( sorry I was hung up)
Your first question. Hope we can help.
There is a thread
http://www.cnczone.com/forums/showth...=&threadid=384 that goes into this feature.
If this doesn't clear up your question let me know.
As with Hu's offer, I too would take a look at your file and give you specific advice. Let me know and I'll PM you my e-mail
