Mike-

Thanks for these suggestions and your kind words. I have added a number of
your ideas to the next release (1.37). You can try a beta copy at:
 http://www.psychology.nottingham.ac.uk/staff/cr1/mribeta.zip
Unless anyone can find a bug, I will release this as the standard download
in about a week.

1.) Done. When you load an overlay, the overlay name and path appear in the
titlebar.
2.) Done. There is now a 'smooth' check item in the 'Overlay' menu. When
this is checked, overlays are resampled used trilinear interpolation (as
before). If this value is unchecked, the volume is loaded using nearest
neighbor approximation (and appears jagged, but preserves a sense of the
true voxel size of the overlay).
3.) Done. When you load positive and negative overlays, there are now 'light
hot' and 'light winter' color schemes available in the Overlay/ColorScheme
menu.
