Resolution test

I'm having some pretty strange problems with my resolution test. The
sample that I'm using is the standard 15% ODCB solution in acetone-d6. The
acquisition parameters are the standard ones, 400Hz sweep width, 0Hz LB
etc. I'm seeing large asymmetric humps below each of the two sets of peaks
from the ODCB which were definately not there the last time that I did the
test.

This has, of course, happened just before I was scheduled to leave for
vacation. I can't leave until the problem has been resolved. Any ideas
about why these humps are now there, how to get rid of them (or at least
minimize them) etc. would be greatly appreciated. Is there a difference
between samples?
