I'm trying to install a single camera. I bring one into the scene, position left-and-right on the X-axis and up/down on the Y-axis. With the camera still selected, I'll go to "Look Through Selected". I get the view. But it'll need adjusting. So I go to Front View...and the camera is gone. I can still see it in the Outliner and the Hypergraph. But selecting it there doesn't make it appear in the scene even if I dolly 'way out. (and I'm in wireframe,) Nor can I now "Look Through Selected". After first bringing it in, any change of view results in it going away. Where has the camera gone to?
