I downloaded and installed PD 9 Pro yesterday and am a bit ambivalent about it at this point. I miss the old GUI and I'm finding the new processes that run in the background to facilitate AutoPilot (which now defrags on the fly): PD91Agent, PD01Scanner, and PD91Engine quite resource hungry. I have left AutoPilot enabled for now, but note that it rendered my computer unusable this morning during an optimization run (invoked while I was away from the computer).
Have you tried this, a-lunatic? If so, what are your thoughts? Overall, I'm sure it's a great upgrade to version 8, but I need to learn how to "tweak" it.
