Hi,

I am trying to use Chimera-X t for solvent-accessible-surface display  (in my system surface display fails almost every time in Chimera).  I managed to get it to work in Chimer-X once  but  now when I click  the appropriate icon on the top in chimera-X menu this icon and most others  (except the one to open files)  are  inactive. Is there anything that I should do to activate these icons?  I am I missing something? I tried selecting the model that was  opened but that didn't help.    

Thanks.
