[Qgis-user] QGIS 2.6.1 Complex polygon not displayed properly

The polygon (there is only one polygon) was created in Golden Software Didger
from contours exported as a dxf file. I imported the shapefile into QGIS
using Add Vector Layer.

The attached image shows how the list of coordinates plot in Excel - it
shows how the coordinates trace round the main shape then go round each of
the inliers (what I am calling lakes) in the opposite direction always
returning to the common point which is the most southerly in the file.

I am confused because QGIS is obviously recognising some of these inliers as
being outside the polygon (it puts no colour in them) but others are not
being recognised.
