Steve,
        OK seems that I did not understand all the details of the pad
straddling a split plane but I was partly correct at least. In other words,
the DRC may not reliably catch the possible faults. I said I was no expert.

You seem to understand the basics of the error message. It is telling you
that some copper on the net "R100_2" is overlapping the split planes. Now it
does not necessarily have to be the actual pad of R100 pin 2, just some of
the copper connected to that pin or net. It could actually be right beside
C43 pin 1 if that component pin was connected to the same net name. If I
were trying to find the error, I would select/highlight the net R100_2 and
then go searching along it's length if it is not readily apparent where the
problem is. Of course you know it is near the split plane boundary.
Alternatively if you select Violations in the left Explorer Pane and can
identify the particular violation in the list, you can highlight and jump to
the error location, "usually".
