I'd expect so. 128 MB seems a bit marginal for S-PLUS 6, at least under
Windows 2000. (We have lots of machines with that spec, including our
teaching lab.)

S-PLUS 6 seems to use efficiently the 512Mb RAM in my machine, but I am
running Windows 2000. (I've seen it use well over 1Gb on a 2Gb machine.)
There have been stories about Windows 95 not managing more than 64Mb
efficiently, but I have no practical experience of that.
