From hansen at snf.stanford.edu Mon Dec 3 10:54:01 2001 From: hansen at snf.stanford.edu (hansen at snf.stanford.edu) Date: Dec 3, 2001 10:54:01 AM Subject: Problem afm2 2001-12-03 10:54:00: trackball won't move in down dir. Message-ID: The trackball has become quite sticky in moving in the down direction since I last used the afm. Although one is still able to focus by moving at a downward angle, direct movement downward is difficult, which makes positioning the sample difficult.
