Hi David,
I sent a pdf to the ml. This is what we observe. Currently we are using
VNMRJ 2.3 but the problem is the same everywhere regardless of the program.
I will contact agilent so that we can find a solution here.

We had to arbitrarily increase the spectal width in the 1H dimension. we reported this to Varian several months ago ( who confirmed this ) and they have not yet fixed the problem as far as i am aware. We assume this a software bug. Would be interested if anyone else has observed this.
