I’m using a grid with some static group by’s defined. Everything works fine, however, every time I choose a new “group by” to view the data in an annoying and empty “Output” dialog pops up. I can see the group by (behind the dialog) has worked correctly. And closing the dialog (clicking the “X”) clears it away and all is good.
For the life of me though I cannot see where or why that pop up is appearing.

Am I missing something really obvious, good people?
