I've noticed that the 68881 version of TurboSilver (V3.01SV, dated 5/5/89)
will not ray-trace a chrome ball correctly on my 3000 (under both 1.3 and
2.0).  The sun's hot spot comes out huge;  adjusting specularity and
hardness does not help.  Has anyone else had this problem, either on a
3000 or with some other math-coprocessor equipped Amiga?  Thanks.

The 68000 version, BTW, works fine.

where or when I will ever use it again.'"

Since then, I've visited my dealer and replicated the problem on his 
3000/25, 2500/30, and 2500/20.  I've also called Impulse; they
hadn't heard of the bug, but promised to look into it.  I just hope,
especially with Imagine coming out, that Impulse takes the time to fix it.
