Dear Freesurfer Team, when I am trying to set control points in tkmedit (FS 5.1 or 4.5) or to see control points in Freeview (FS 5.1), I run into a strange problem when I connect to our server through X11. Namely, I cannot see the control points, although they are being set when I place them (they are saved in the respective .dat file). When I switch to a mosaic view, I can sometimes briefly see them, but as soon as I try to place new ones, the old ones disappear again. Any known workaround (apart from using VNC)? Thank you very much, Caspar
