Can you give me a recipe to replicate your problem. For example, this is what I tried, but it seems to work fine on my MacOS 10.11.6 computer:


1.) File/OpenTemplate/ch2Better
2.) Choose Window/Multislice
3.) Choose View/Overslice/20%
4.) Make sure View/OrthogonalView is unchecked
5.) Make sure View/Orient/Axial is selected
5.) Choose View/Slices and enter the seven axial desired axial slices "76, 92, 108, 124, 140, 156, 172, 188, 204, 220, 240" (corresponding to MNI coordinates -32, -24, -16, -8, 0, 8, 16, 24, 32, 40, 50).
