There's one set of circumstances under which I'm sure that will happen: the service is not running and the (one) instance of EVERYTHING.EXE is running elevated. The service running, or not, may be irrelevant. This is because the inter-process communication needed to open the options dialog is, by default, disallowed between the different integrity levels. I discussed this with the author in an Everything forum. While the elevated instance could allow the communication, he did not seem inclined to make it do so.
