Bests & Worsts Reviews from Amazon

I have used Dragon for years and couldn't work without it, but Dragon 13 (Home version) is hopeless on Windows 8.1. It runs so incredibly slowly, I can read the newspaper before it finishes a paragraph. I'm totally frustrated. I've played with settings and fine-tuned it repeatedly, with no improvement. I'm going to have to go back and buy 12 again (I used up all my installations of the previous disk) to get my work done. Adding an update a few weeks later: I purchased 12.5 (again) and installed it. It works fantastically, right out of the box. Fast, incredibly accurate, a joy to use. What on earth happened with 13? I see that the price has now been reduced to half the original price. Save your $$ and go with 12.5. THIS is the Dragon I know and have loved! P.S. If the Nuance representative who has commented on other negative posts is reading, I sure wouldn't mind a refund of the $100 I spent on 13, which went straight down the drain.
