Has anyone tried ZoneAlarm Pro 2010 on Windows 7? Any problems?

I've seen the disclaimer which warns that

> For those who wish to run ZoneAlarm on pre- released

But I'm only interested in running the firewall (thus my interest
in ZAP :-> ). Any other features of the firewall alone that I might
expect to bite me?

Thanks!
