It's amazing how easy the simplest things can have a profound effect on choosing software. I can no longer provide a dwf to my customers/clients because they don't understand the simple concept of when they print you must switch the dwf to black and white instead of color because certain items don't show up when printing in color. It looks like they are so happy with the black and white pdf's that they see no benefit to the dwf format. How do you address these trivial things to people that just don't get it?
