I've submitted a bug report to tech.
I had cause to seek out some data for Africa today and went to the DCW data initially supplied on Manifold 7 DVD in Manifold 4.5 format. It imports into 9 as Pseudo Mercator, assigning the correct coordinate system of lat / long seems to distort the coordinate system and it will not display in a map with a Bing image, for example.
If I import the same M 4.5 drawings into M8 first, they are correctly positioned and assigned the correct coordinate system. If I save the M8 project, then open that in M9, all is fine. Coordinates for the same part of the data are highlighted in the screenshots.
