Props giving of fluorescent colors

Ever since upgrading to DAZ 4.10 I have problems when I load a prop into the scene. Look at the attached picture. The viewport gets dark and all the surfaces appear in bright fluorescent colors. It happens to almost every scene (kitchen, home, laundry, bedroom, etc) I load into the viewport. Oh let me tell u when it started giving problems. One time I decided to change the color and/or opacity of the bulb using Surfaces (color) tab. Since that very moment all the scene items have started to appear like that. Can somebody tell me how to fix that? Thanks

The attached image is when I have only loaded a scene into the viewport
