they acclimated only one week before
the finishing work. However, the wood had been delivered to our house a
week before installation began.

The finished floors looked amazing--smooth, tight, beautiful. About two
or
three weeks after finishing,

The flooring company says these cracks are
the normal results of cold(er) weather shrinkage and should close up again
somewhat as weather warms in the spring. But I'm concerned. The vast
majority of the cracks/separations are less than the thickness of a credit
card. But there are at least a dozen that two credit cards would fit
into,
and two or three that I can pretty easily fit four credit cards into.

My questions: are these separations indeed normal, particularly in a mild
climate where nighttime temperatures don't get down much below 38? Can I
actually expect the cracks to close back up in the spring (and then,
presumably, open up again next winter)? Did I lose any right to complain
by
not waiting the full two weeks between installation and finishing? What
options do I have, as regards the appearance of these floors?

Wood moves along the width of the board, not the length. This is somewhat
normal. It probably will expand in the spring. You may want to consider
running a humidifier in the house if the humidity is much less than normal
for your area. It may take some time for the wood to swell again.
