If I don't check on screen, I can write comments as I need and comments are displayed only when a function module is selected (Block properties-Comment). When I print even if Tools> Options > Print > Comments is unchecked. Many comments are printed on pages ( in a almost random position) impairing the readability of the page; no matter if I use a solid printer or I make a .pdf file.
I am using Windows XP SP3 as operating system.
