Ok. try the file again, and tell me what happends. You can enable it at sea, i just don't know if it will take effect right away or not.

Same D/L link, just an updated file.
I was unable to totally remove surface contacts.
It came down to this.
Min height of 8.3025. I only detected half of the planes that were present, and what contacts i did get were MOSTLY intermittant.
Min height of 8.3 , i detected all of the planes present, and later on picked up a couple surface objects as well.
WIth a Min height of 8.35, it pretty much stopped working.
It's THAT sensitive.
