I just started using Notes 8.0.1 this week. Some things I love, and some things annoy me.
Like this one:
I was working on a calendar-entry, when suddenly the classic client popped up. I can't close it by itself. When I close the standard client, this closes as well.
Don't know if this means that the classic client is used as a go-between for Domino Designer/old Notes apps and Notes 8 Standard Client?
