Hello,
 
I've run into a problem when trying to view surfaces. tkmedit works fine but tksurfer gives an error saying "Window type not found". I see that others have had this problem in the past but the solution didn't work, i.e.
 
setenv doublebufferflag 1
tksurfer ...

I'm using a brand new quad-core machine with independent graphic memory, running Ubuntu and the CentOS 4 x86_64  V4.1.0. version of Freesurfer.
 
Any help would be most appreciated.
