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.
