Thanks Ed, and all others that responded. I thought I had read this before about removing the code after compiling. I also understand the debug issue, but we do the debugging ourselves and have the unmodified versions ourselves.
BTW, we tested the drive map stuff you helped us with today on the WAN out on the west coast, worked like a charm.
