Yes, I am using gnuplot; should have mentioned that.  As a workaround 
for the legend font size, I found that it still works to set it while 
printing with 'F:SIZE'.  I'm not sure why setting the location outside 
no longer works, but all the other location strings are fine; I recall 
it working in 3.0.x.

Depending on the plot and other print options, sometimes the '-tight' 
option works, and sometimes it doesn't.
