[chimerax-users] maps not on same grid in new ChimeraX?

Hello, I recently updated my ChimeraX to version1.4(2022-06-03). It seems that now when I open cryoEM maps they are not always opening on the same grid, although they have the same box and pixel size. As I recall, in previous versions of Chimera, maps with the same box and pixel size would open in a coordinated, overlapping fashion, and they would move together when manipulated. Is there a preference that I need to set in the latest version in order for this to happen? Thanks for your help, Michelle
