Hi Johan, I have now written an osg_atof function and placed this in src/osgDB/Field.cpp, this is now used in the Field::getFloat methods that the .osg plugins uses. This new function always assumes that a '.' is a decimal place.
Could you do an svn update and let me know if it works fine. Cheers, Robert.
