Sounds reasonable, but i would ask .
If this are the case, Then why would the default lighting on someone else's computer show the geometry just fine?
That once more leads me back to the problem that it is most likely something with my computer.
Non the less, i have for the moment decided to move on and ignore it, since the final product of the model is not being effected at all by the view port issue.
Though if someone can come up with a solution, please feel free to share as i am stumped at the moment.
thank you for the response though JS,
hope all is well with you mate, been a while since we spoke for any length.
