The plot thickens.
Here is what I did, using the macosx_10.5_Intel_64 binaries archive that is on the website now:
suma -spec N27_both_tlrc.spec -sv TT_N27+tlrc. &
afni -niml &
press 't' in suma
open axial window (TT_N27+tlrc is the default choice for both overlay and underlay).
press 'See Overlay', and that sent colors to suma just fine.
Can you follow the same sequence and let me know how that goes?
You may need to upload your data for me and an exact sequence of events.
Just to be sure:
afni -version gives:
Version AFNI_2008_07_18_1710
[[Precompiled binary macosx_10.5_Intel_64: Nov 19 2009]]
