I am not able to visit as often as I would wish, however, I did pick up the tip that there was an update for Acrobat 6, this has now been installed ( thank you for that ) and tested and frankly I see no difference at all. So I will as soon as I have a chance continue my look at alternatives. Perhaps some of the fault is mine ;-) some of the type is only 4pt but what annoys me is the inconsistancy, some is fine and some is not. Will try Ghost first as this one of the alternatives that I have not tried yet.

many thanks again for all the suggestions of help.
