I'm not sure exactly what is going on. I just set out another
email and I can't get this one data layer I've created to
calculate correctly. I chalked up the one yesterday to fat
fingering the acreage. Today - I've done this quite a bit it's
consistently wrong. Linux - it's right. I'm going to reboot. Go
for a walk. Come back and try again. <br>
<br>
I'm going to do a series of tests to reinforce it's me - I've done
some things but I haven't been consistent between platforms. <br>
<br>
This cat isn't sneaky but sleeps on my desk....<br>
