Thanks David!

The second link gave me at least a partical answer.

"Page Break Preveiw" was turned on. Turning this off seemed to speed up
things considerably.

Now tasks happen immediatley or only take a couple of seconds.

The question for me is why does it do that on just this one machine. Other
machines handle the file just fine with no delays.

I will keep looking.

With a new install of Excel every task is taking 15 sec. to complete. I
timed it - all the same amount of time from opening a file, unhiding columns,
moving rows....

Reinstall fixed it for one task. Everying else on the computer runs normally.
