There seems to be a difference in which IDL5.6 and 6.0 handles fonts.
IDL6.0 does not appear to be consistant when displaying characters in
size and alignment. For me, new lines do not always line up
vertically. In addition, lines with only text, (i.e. no numbers),
seem to appear smaller than do lines with text and numbers. Has
anyone else encountered this? And if so, have you found a way to fix
these problems? Or maybe know what IDL is doing differently? I've
appended a small test program which illustrates my problem.
