All,
Having just read the article in the current issue of FW entitled, “A Benchtop Bench”, I have one question concerning wood movement. In a temperature and humidity controlled environment & having used properly dried wood, will wood still move?
Thanks,

You need to define "controlled", but generally the answer is yes, wood will still move.
The problem is that
1) wood is hygroscopic (it attracts moisture to its surface) and
2) the porous structure of wood causes the attraction to vary with temperature and humidity.
The only way you could stop wood movement would be if the temperature and humidity were absolutely constant. (And I wouldn't be surprised if someone came up with a reason that it would move even in those conditions.)

dlb,
It's interesting you mention the Bench Top Bench, I just finished cutting all the M&T's on mine. Yesterday morning I glued up the top using some poplar that has been sitting in the shop for about 6 months. This morning the top has warped about 1/4" on the diagonal. Normally I would have waited about a week or two after resawing before glueup...but I am in a rush to see if it's handy. If it is, I'll redue in maple.
dlb,
In a perfectly controlled environment wood is very stable.

The problem is that humidy control is only done for special applications, meaning your normal AC or heater system will not control humididty.
