Hi Paul,
I had never tried copying multi-page selections of text from a pdf with Acrobat. I have Acrobat X Standard. When I tried pasting from a pdf print of a web page, I got the typical problems with pasting directly from a web page like every line becoming a paragraph.
I then tried copying from "Word 2003 Visual Basic Programming" by John Low which is a e-book and got essentially gibberish like:
________'_'__'________7______F_
#A ___9'___E=____'_______G_
_A ____'__'_______"_
I then tried on a scanned police report and got very poor formatting including loss of columns and a paragraph mark at the end of every line.
I guess I would not recommend it but then I am not using the Pro version.
I found a this site to download Acrobat 8 Pro and will try that.
