We use 2.0, which might account for the instability, since
x.0-versions tend to be "immature".

I don't prefer Win98 over 95, but what I want is a real operating
system, e.g. Windows NT /2K. Unfortunately there is no mention of NT
on the disk (but it starts installing itself on NT, as I just tried).
Does anybody know if it works?

Indeed.

ACK.

all (but I'm not sure with Excel export)

Yes, for that price it's really okay.

But one thing that does annoy me very much is the limited possibility
for scaling graphs. If you elute with a buffer that has some
208nm-absorption and want to look at trace peaks over a buffer
baseline of, say, 0.3 OD, you run into problems. You can scale from 0
to 0.5, and you'll see your gradient (and major peaks of course), but
not small peaks, or from 0 to 0.25 (don't remember the exact limits,
just an example), and you'll not see anything, because the baseline's
over 0.25. What I would like is 0.25 to 0.35, but that is not
available.

Bye, Frank
