OK! I will leave it. Thank you very much for your help. It has made a major difference that I can now mouse wheel scroll through the document smoothly. I will check in once in a while to see if new answers have arrived --- unfortunately, I first send the question, then signed up for the list, which means I do not get answers to this thread, hence the lack of order in the thread as I can only reply to my own initial mail ;) Again, thank you!
