Hi John,

Yes, you and others in that thread seem to be experiencing the same
problem, although there are also different issues discussed there.

I'm a bit surprised... With the popularity of python I would expect more
org users to have run into this and it to be fixed, but perhaps it isn't as
widely used as I thought. Anyway, it is now usable even if the 'print'
statements don't show up.

  -k.
