[ Ales here, I'm reposting this since majordomo didn't recognize the

I have solved this problem with this "hello world" vpi and it now makes a 
bit more sense.
If people are interested I will post the real version or I might put on
my web site so that other don't have this problem.
My later problem with handles still exits but I cann't see that mail
at the moment. I might be because I am away from my usual site.
I will check on friday.
