Had a CD through the post today - hp software driver - couldn't get any advice, so put it in.
Maybe I'll come to live with it, but it's changed my whole procedure for editing etc photos & probably more besides, when I catch up with it.
Doesn't tell you why you need it or what the penalties are. Seems much quicker, but I actually liked the old system very much!!
DON'T PANIC!!
Now find it's merely an update of HP Director & Photo Imaging. Had me worried!
