I'm still subscribed and the main original developer but my time is limited and labpython
is not at the top of my priority list.

I will take a look at the mentioned patch when I have some time and see if that might be
the problem. I'm not specifically aware that I used something called recursive traversal.
Instead I suspect something strange going on with the Python thread protection or session
management. Above mentioned patch might have some indirect influence on these things though.

This might be a hard one to fix. I suspect some issues with standard IO clashes as python
is really called as a client inside the LabVIEW process and as such as no default standard
IO anymore. Maybe that one could provide some standard IO redirections going to dialog
boxes or such but that seems like a huge hassle.
