I'm still getting the same bug that I've reported to Novell with the SP2 client.

If you post a recurring appointment in Plain Text and want to later edit the body of a single instance, it changes all instances. If you try the same with HTML it changes only that single instance. I've confirmed that the default action in the 7.x clients were a message prompt asking This Instance, All Instances, This Instance Forward, or Cancel.

This bug is a deal breaker for my site to deploy any 8.x client as a large number of our managers attend recurring meetings and update the details of the individual meetings as each one gets closer.
