I am not sure if this is a bug or a fault with my installation I have been up to recently using Version 8.03 and have changed to version 9.03. When I rectified a fairly distorted scan of a paper map I noticed that the results were not as good as usual . I usually use 9 GCP on the map and leave the rectification method as automatic. I however noticed that the GCP were moving which as I understand it should not happen with 9 points as the automatic method should select the triangulation method of rectification. When I tried to manually select the triangulation method of rectification I got the message " can not load TriangulationLib.dll " what am I doing wrong ?
