On the off chance that you are using a Mac - I had a similar issue with X11 and tksurfer becoming unresponsive at the tkoInitWindow stage. I think this is because a recent OS X update broke X11. This update (from X11 2.5.4 to 2.6.5) fixed the problem for me:

Dear Freesurfer experts,

I have a problem with Tksurfer. Whereas this worked previously fine it suddenly crashes every time I try to start it. This happens with every subject or fsaverage.

A similar problem was reported before with similar terminal output but unfortunately I could not find a solution to this problem in the mailing list.

Any suggestions are welcome!

Hi Michelle,

hmmm, no idea. Do you want to upload the the subject and we'll see if we can replicate the problem? Do you have enough memory on that machine?

Hi Freesurfers, I've been using Freesurfer for a while, and have had no trouble with launching tksurfer. But recently I have tried to view an inflated hemisphere of a subject I have had no problem viewing before. The window no longer opens. This the case for all of my subjects, with whom I have had no previous problems.

Any suggestions would be most welcome.

Thanks very much. Michelle

Below is the terminal output. After this it just returns to the prompt without any error message..
