according to the what's new section there should be a persistent chat now - this doesn't work. After a new login all chat's are gone.
did you get any news on that?
I talked with djwilliams722 about this issue and it looks like we'll need to dig deeper. Would you please open a support ticket so that we can engage all the right people?
You can easily open a ticket via the support site here http://www.lifesize.com/en/support/contact-support.
if i login with my windows client (win7) i can see my chat conversations i had before on my mac.
What windows version are you using and did you tried also to reinstall the cloud client?
