Re: Exception in p4p

Hej again,

sorry for the noise.

It seems as if my script picked up the wrong library.
Not sure why, that is another issue.

The effect was, that I had 2 "virtual env" -
after updating both, it looks as if the problem has gone.
Re-testing on Mac to be done.

Thanks for the help and the patience, Michael.
