400 ps is relatively short, especially given the speed of current hardware and 
of Gromacs 4.0.  I generally see longer time periods in the literature.

Then you are not getting the separation you described before (>2.5 nm).  It 
looks like you are only pulling a distance of 0.17 nm total.

The best way to send this information is to generate image files and post them 
to a free site where others can see them (photobucket, etc).  Up to you to 
determine whether its necessary.  At this point, I think you are just not 
getting what you think you are setting up.
