In 1.8 if I load the dataset it opens at a scale of 1:5325654358. If I use the pan tool and just click on the map the scale changes to 1:631588609, then 1:2918610855, then 1:2934133484 and so on. Distance measures seem unaffected. It seems to be being caused by the units of the project being set to degrees. I have saved a project and the units are set to degrees. If I open an old project up it opens at the correct scale. In my old project files it is set to metres. (see examples below). It seems I have to make sure Enable on the fly projection is unticked in the project properties, and then manually set the Layer units to metres in the general tab.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I was also having problems a while ago with exporting to MapInfo but I have just tried this and it works.
