No, as far as I know, this ICC account Queen(C) is not mine. I still have to come to grips with ICC. As for your question 'how long...', well, I started more than a year ago. I will try to display the pv while thinking in the GUI version as well, and will also carefully consider your other suggestions. It seems to me you spotted exactly the weak points of my program, which is what I hoped for! Leen
