Sorry that all I can offer are suggestions as I am in the US and can't create a complete environment to test. I did notice that in the User Settings dialog there is a information pop-up next to the Thousands Separator and Decimal Symbol labels that say "Applies to all numeric values except data in Results grid". That may explain what's happening. A solution might be to convert the numerics to string so you can cut and paste cleanly?
Guess there is my answer. Would still ope in copy-pasting those it would work. Your solution probably works as well, but then it is probably easier to make an extra output file. Use the results grid for checking/ debugging, so quick references... transforming them to strings to be able to look does not really help then. But appreciate the suggestion / help... solution probably is to change my regional settings for my full computer :(
