Consider any script with output long enough fire up the pager, and
doing a plot (example below).  Now try to close the plot window. The
menu drops down, but the window refuses to go away (also C-w does not
close it). Finally go to the command window and page through all of
the output.  When the output is finished, the plot window disappears.

for i=1:npts
  for j=1:npts
