note that some of the periodic Mac updates overwrite X11, so it may be necessary to reinstall XQuartz. i had to do this recently myself because of a recent Snow Leopard update.

send a question that martina asked before and we have not solved the prob.

on macs when we run tksurfer xxx lh inflated for example the surf comes up looking smoother,low resolution rendered. if we load something like curvature that displays in color the surface looks fine, so the problem is only with the grayscale surfaces.

this occurs on all the macs in a psychiatry dept. lab,other macs at other labs around the surfs always appear normal, i have never seen this problem before, the machines used to display the surfs normally and then all of a sudden it started happening all the time on this one group of macs, seems it must be associated with some config change or upgrade,but i am not much of a mac uses, i use linux.

anybody out in freesurfer land seen something like this and can give me a clue ?

thanks
