After doing a search, the attribute pane (a.k.a task pane) is replaced by the search results. That's good. After reviewing the search results, I click on View -> Task Pane to bring back the attributes. The search results go away, that's well and good, but instead of the attributes pane coming up in its place, the editor expands and fills the space. Try again: View -> Task Pane. Instead of the attribute pane, the old search results come back up again. To get the attributes pane again, I must exit MI and restart it. This seems to be a bug.
I see that View -> Task Pane either closes or opens the Task Pane with the last shown window (attributes or search results), and the user needs to navigate to the other window if desired.
