Apparently it's not something that's happening at this very moment.
But don't get hung up on the present progressive (-ing form): Dutch doesn't normally use that, which is valid for quite a few other languages. When learning a language different from English, it's no use to try and find out why English uses either of the present tenses, as the Dutch will just use "present tense". I would say you're better off pretending there simply isn't a present progressive in English either. It confuses the student less, and allows paying more attention to the Dutch you're trying to learn and less to the English you're merely using to learn it.
