But in windows xp it was weri possible. For example I have a pdf file with ip header structure, in the first page i have the stucture itself visualized and in the next 20 pages I have all the fields explained. So I want to open that file twise, one just to show me the structure and another opened to some 16th page so that I could see and structure and read about that field.
I think there should be oportunity to open that file again, for exemple in read only mode.
