Hi Martin, I don't use grass with qgis much but I do have a guess. When you look at your installed programs, is it possible there are options for "qgis" and then also a listing specifically for "qgis with grass". Different operating environments might explain why you can't import from grass as expected when opening gui qgis.
Hopefully someone has a more informed suggestion but this seemed worth mentioning.
