COMMENT: From Chris Hinch (chris@dcc.govt.nz):
I heard comments on comp.sys.opengl that, at the moment, the Impression Plus doesn't have "true" OpenGL support under Windows NT. I don't know if this is correct or not.
From Blair MacIntyre:
This is partially true. Someone from Microsoft posted saying that NT 3.51 will include the appropriate driver for OpenGL for this card.
