Its a bug that effects only certain mantissa (23 are known so far) when doing a floating point divide (double precision). PGP doesn't use floating point for its big-numbers and it has no need for double precision. Since most version of PGP compiled for Intel platforms will be or the MS-DOS or Windows variety then it is very unlikely that even floating point instructions will be used - emulations libraries will be used instead for floating point. NT is a slightly different matter - but as I said PGP doesn't use floating point for the key generation or ANY of the RSA/IDEA code.... An interesting point about this rather obscure bug though. It won't effect over 99% of all Pentium machines in use. It won't effect word, windows or any of the other numerous programs that hold a large market share and high-usage stats.... but people making a big deal out of this and demanding fixes (I have heard new Pentiums don't do this and am going to test this next week) could cost Intel millions potentially..... and I doubt whether it would effect PovRay or whatever things people might actually use floating point for anyways.... Serious scientific work could suffer severely, and since Intel boxes are good power for dollar there are quite a few used in various places for intensive calculations.... (e.g. seismic ray-tracing - but that done of 486-DX2-66 machine because here is NZ they are about half the price of a Pentium so are even better value for money). Chris
