Well, I just updated my graphics driver and as far as I can tell, there's no improvement. Luckily, the functionality of Wings3d is still there, its just harder to see what I'm doing. Ah well.
My advice is, try temporarily ignoring the phantoms. If you export the model and it looks fine in openbrf and in game, then don't worry about it too much (I know, its a pain, but at least it works, right?)
