It's theoretically possible for 3DS to be hit by the Pentium bug. Product
Support has not seen one case of it. ACAD product support, (ACAD uses double
precision math vs 3D Studio's single precision) has not seen a single error
that can be attributed to this FPU problem.
There is a lookup table in the Pentium which is accessed when specific
combinations of numbers are divided. The lookup table does not have the
correct info in this table and the error occurs.
Gus Grubba has made some good analogies about this problem and the likelihood
of it occurring. (So far, I haven't heard of any Lottery Jackpot users with 3D
Studio!!!)
Autodesk has a FAX back system about the FPU: 415/507-5595. Select option 2,
after dialing this number, and get document number 852.
