When I am trying to construct a syntax query, I place an item and then I click the + symbol to place another. The right side column changes to reflect the selection of the new element but I do not see the addition of the newly placed element. When I close the Syntax window then reopen it the element is visible.

In the above screen shot there is a Clause and a Clause Component (note the title of the right side column title, but no Clause Comp to the left).

Now (above screen shot), the same window after I have closed and reopened it, having done nothing else. It is like the CC is not visible until it is closed and reopened.
Is anyone else having this problem? I have not seen it mentioned before.
