View Shaded no longer rendering

[Cosmic Creepers]

Hello all! I've been an avid SU user since v3. I meticulously use layers to help in performance during building. My current model no longer renders shades. Colors, yes. Shades, no.

I've toggled all Face Style options, Preference Open GL options, shadows, etc. No change. All is fine in new windows/models. I only work in active layers keeping little hidden to help the active geometry.

Scratching the heads here... Have I possibly reached model size that no longer renders shades?

Any suggestions?

Thanks!

Two possible reasons come to mind. Do you see this in all models or just one?

In Shadows, is Use sun for shading enabled? Are the Light and Dark sliders crossed up? That is, is the light sider all the way to the left and the Dark slider all the way to the right?

The other possibility would involve the graphics card. What kind is it? Did this shading issue just start suddenly? It could be that Apple pushed an update to the graphics drivers in a recent update that caused this problem. If the Shadow settings don't fix it, go to Preferences>OpenGL and turn off Use Hardware Acceleration, Is there a change?
