Hi Barry -
I have had a lot of RW crash problems also.
I think it is related to the NAAPhong issue
that VW folks need to work out.
Also, I have found RW will crash the program
if I have two textured objects superimposed
in the same space -- such as two walls that
inadvertently are being displayed in the same
location in a linked model.
Check your model to make sure two textured
objects are not superimposed.
Good luck.
