Recently added an oes11 server to my tree, it's a mix of oes2sp3 &
oes11. After all the updates, etc, I cannot get yast to start.

Let me clarify, it will not start via the 'computer' button. It will,
however, start from a command prompt.

Kicker on that is, if I start it via a command, I cannot configure
anything, as when I try I get the error:

** (y2controlcenter-gnome:8380): WARNING **: key not found
