I appear to have installed it correctly, but the graphics will not
display. I can issue figure and plot commands, and do not receive an
error, but I do not see any figures. I can even issue get(gcf)
command and get a complete list of the properties, but I cannot see it.
Note also that icons in the applications folder have the 'NO' icon on
top of the application icon, the one with the circle with the cross
from 11am to 5 pm.
