What is the probability of a successful trial factorisation in the range of
exponants currently being given out (16-17M)?
Are the estimates given by the program for p-1 factorisation accurate?

I'm not adept at the number theory, but presumably these are more likely to be
prime for no other reason than because they are relatively small, and the
density of Mersenne primes decreases with size.

I assume that means that it forgets that a result has been returned. The

Better would be to include in your start-up scripts code to copy the data
files from your prime95 directory into your mprime directory, while copying in
the reverse direction when you shutdown.

NT/ME But I expect something
similar would be possible. WIN95 and earlier can't be secured in this way.
I would also suggest - if it hasn't already been done - that the message
handling routines in the client do as much sanity checking as possible, and
abort the program /before/ returning
