Sorry but 19 isn't ready for prime time. My VMs are pausing randomly and it makes getting work done very interesting when it snaps back and all the sudden everything you did gets applied instantly. Especially when working on large Excel spreadsheets and you moved the mouse when it comes back your somewhere else entirely different than you expect. This never happened under 18. Just want to make sure it's good to switch back without destroying my VMs. Thanks for any help you can give.
