When you Button-3 click on the colorbar, do you get a menu at all?
If you do, keep holding down Button-3 (so the menu doesn't disappear), then move the cursor to the menu button at the bottom of the menu, then (still holding down Button-3), click Button-1 on the button. This requires a fair amount of mousing agility.
If this doesn't work (it works here), I'm not sure what to tell you. I don't know why this problem occurs on Solaris 2.8. You may want to try compiling AFNI yourself, but that will require installing a C compiler. You can get free stuff like gcc from [
www.sunfreeware.com].
If Button-3 doesn't work at all, I'm pretty clueless as how to help you.
