You're right, that there are two ways that the event (X,Y) is calculated, and in
my case, the first branch is used [ if (getCameraWithFocus()) ]. If I comment
out this branch, then the (X,Y) locations can be used correctly (after
transforming them back). One of these two branches will be used, since
pointerEvent is set to true earlier.
I don't think I'm doing anything special with my camera setup (looks pretty
plain vanilla to me),so I'll have to look into it a bit more. Thanks for the
tip.
As a note related to osgWidget, you might want to also keep this issue in mind -
the mouse X,Y can be transformed in a different way, depending on a setting
related to the camera.

I'm just using fairly standard settings. To get CEGUI to render last, I've done
a stateset->setRenderBinDetails( 11, "RenderBin"); for the group containing
CEGUI. As well, I'm using singlethreading for drawing. The rest of the code I'm
trying looks pretty standard...
mViewer = new osgViewer::Viewer();
osg::ref_ptr<osg::GraphicsContext::Traits> traits =
new osg::GraphicsContext::Traits;
osg::ref_ptr<osg::Referenced> windata = new
osgViewer::GraphicsWindowWin32::WindowData((HWND)this->Handle.ToInt32());
// Setup traits
traits->x = 0;
traits->y = 0;
traits->width = this->Width;
traits->height = this->Height;
traits->windowDecoration = false;
traits->doubleBuffer = true;
traits->sharedContext = 0;
traits->setInheritedWindowPixelFormat = true;
traits->inheritedWindowData = windata;
// graphics context
osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
// new camera initialization
osg::ref_ptr<osg::Camera> camera = new osg::Camera();
// Assign Graphics Context to the Camera
camera->setGraphicsContext(gc);
// camera viewport
camera->setViewport(new osg::Viewport(traits->x, traits->y,
traits->width, traits->height));
mViewer->addSlave(camera.get());
mViewer->setCameraManipulator(new osgGA::TrackballManipulator());
