I have never been able to get PD to work properly on my MB for running Windows. It's always been unusably slow and I've tried periodically to fix it using advice from this fine forum but to no avail. I upgraded to PD 12 when it first came out but that made it worse if anything. I'm starting to wonder whether my speed expectations are simply too high and I should just give up on it. Can anyone else share experiences with this kind of configuration so I can see whether it's still worth putting effort into trying to fix it? Years ago I used to show off to my friends that I had Windows XP AND Windows 7 AND OS X all running happily together at speed on my ancient MacBook Air. But it ain't like that any more, not even close. Did it actually get that much worse or do I have something horribly misconfigured? Thanks for any help!
