Patrick,

I had similar problems. They occurred when I used multiple expressions in one cell,
one on each line. When the notebook was read back in in Version 4, Mathematica could
no longer parse the expression. I had made it a practice of putting an extra space at
the end of each line in Version 3. Version 4 did not like this. After I edited them
out things seemed to be OK. When I contacted Wolfram support they seemed to indicate
that there was a problem without commenting on the exact cause. I don't know if this
is the only thing that causes the problem.
