I’ve noticed that sometimes, when typing table names in the object explorer, when the focus jumps to the table the Viewer does not synchronize to the correct table selected.
It doesn’t seem to matter if you hit “Enter” or not once you’ve got the right table selected.
In this screen capture you can see a different table name shown in the viewer than is selected in the object explorer.
Problem seems worse when jumping between tables in different databases on the same server.
See the screen capture for an example.
