Hello,
where exactly you get this problem? could you please explain me again the steps you take in order to have the issue? thank you

***** Google Translation:

Hallo,
wo genau du dieses Problem? Könnten Sie bitte erklären mir noch einmal die Schritte, die Sie ergreifen, um das Problem zu haben? danke

surely, I can...
When I describe a problem in the forum it would be very nice to mark a word or a few words and than, with drag and drop move this words to the subject of the article or to the array of tags.

Hello,

I see, this operation is permitted thanks to the operating system and normally you can use it.

I didn't get where you couldn't use it, I tried in the page for adding a new post in answers and it actually works (using chrome).
