This is a feature and a bug.  The feature part is that Werner Bruhin
added a patch to "gray out" the forward and back buttons when clicking
them produces no effect.  Eg, if there is no back (your first view of
the figure) the button should be grayed out.  If you navigate
somewhere, the button will be enabled.

The bug is that on win32 with wxpython 2.6.1 instead of presenting a
grayed out version of the button the button is a solid gray rectangle,
and it is visually  very disturbing to see it toggle between an arrow
and a gray rectangle.  On linux with wx 2.5.3, the arrow button still
looks like an arrow, but is gray to indicate "not enabled"

Does this feature work properly for anyone on windows?  Other
WX/Windows users, please send me your wxpython version numbers and let
me know if this is working for you so we can file a bug report to the
wx list.  You can get your wxpython version by running your script
with 

  > python myscript.py -dWXAgg --verbose-helpful

Thanks!
