Differing behavior with linked files

With 1.8, when I clicked on a linked (the little lightning bolt) OmniOutliner document, it immediately opened the document in OmniOutliner.

With 1.9a, when I click it, it shows the document in XML and I have to go up to the menu to open the document in OmniOutliner.

It would be nice to be able to edit outlines directly in DT, but barring that, is there anyway to go back to the old behavior ?

Both “Launch Path” and “Open Externally/Open With…” should launch OmniOutliner (these two commands are identical for file links).
