Hi Seb,
I am completely lost here. I tried the disconnect,
and as I was expecting the render window is
gone and I do not see any visualization. I would
guess I will need to reconnect again.
The view id is the same before and after.
The datafile is correctly changed though.
I guess that is the problem ?
