My company recently upgraded to Acrobat 8 from Acrobat 6. Maybe there are some new tools that I don't need to use yet. But in general, I'm unhappy with this upgrade. The OCR takes longer. When extracting pages, I get a strange "in use" error seemingly randomly. Then half the pages disappear into the ether and half stay on the PDF I'm extracting from. The new PDF is not created. Be very careful to check before you save anything you do! Guess I'll just have to slow down and be less efficient thanks to this "upgrade."
