Details:

I am working with a fresh installation of Octave 3.2.4 with Gnuplot 4.4.0
downloaded from http://octave.sourceforge.net/ (MinGW binary distribution) on
Windows 7 Home Premium 64.  During installation I installed with the SSE2
options and all Source Forge packages except oct2mat (following instructions
to allow figures to be generated correctly).  I noticed the following
unexpected results when testing some scripts developed in Matlab.  I am
uncertain if these behaviours are actual bugs or 'features', but the behaviour
is different from that of Matlab in identical circumstances.

1) When an axis label ends with a subscript or superscript, the entire text
of the label has decreased font size.  For example, plot(1:10); xlabel('all
text is made smaller_0'); produces a small text label, whereas plot(1:10);
xlabel('all text is made smaller_0 '); produces properly sized text.

2) When the y axis is labeled, a subscript or superscript will overlap the
text is is supposed to follow.  For example, plot(1:10); ylabel('subscript
overlaps this text_0 this too'); produces properly oriented and sized text,
but the portion following the subscript command ('0 this too') overlaps the
beginning portion of the label text starting at 'this text'.  Note that this
problem occurs with the default figure dimensions (approximately 1:2 on my
screen).

3) When the figure is manually resized (by clicking and dragging on the
corner of the window), both x and y labels which contain
superscripts/subscripts do not move as single units, but are broken up into
blocks of text of the same font size.  These blocks are anchored to the
figure, not to each other, so that stretching the window causes the blocks to
separate and compressing the window causes the blocks to overlap.  The figure,
when refreshed by typing the command 'refresh', reverts to proper block
positioning (though still subject to the deviations 1) and 2) above).

I have found no mention of this problem over hours of searching online and
through the bug tracking system, and am therefore suspicious that this may be
a problem particular to my setup/settings.  Any help clarifying what options
may be changed or what other workarounds may exist would be greatly
appreciated!
