>So are you saying that "This" could really be "That"? This would explain why in a gotfocus of another control in my grid, sometimes a property that I am referencing by using "This." gets set in the object I'm leaving, instead of the object I am entering.... Hmmmmmm.

No, that's something different. In my old post, I was only referring to the fact that a page tab can appear selected (with dotted lines, like it has focus), at the same time another control actually has the focus.
