Hello,

Has anyone else had problems getting single-pixel lines to come out?  I
can get dots and area to come out great.  I am using 100 for areas and 0.4
fAs for dots.  For lines, I have tried everything from 200 pAs/cm to 3000
pAs/cm.  I only got some lines to come out once and that was with great
focus and doses greater than 1200 pAs/cm.  My understanding is that
300-360 pAs/cm is the normal range.  Does anyone have suggestions for what
may be wrong?

Thanks,
Scott
