I'm not sure if its just your screenshot but the perspective and aspect ratio seem off. Do you have your graphics drivers up to date? It's possible this is a graphics driver issue so worth checking.
Also, is this Gizmo problem only happening in this one project or all projects? So for example if you load up one of the sample projects that come with iClone do you still have the same small Gizmo?
