Juergen and Scott,
I found and fixed the source of this bug this afternoon. I've posted an updated tksurfer.bin for the Intel Mac Leopard here:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/fsdev/nicks/dev/macintel
Copy it to your $FREESURFER_HOME/bin directory, and type: chmod a+x $FREESURFER_HOME/bin/tksurfer.bin
For other platforms, the fixed tksurfer will appear in the next freesurfer release, or i can post the binary on the ftp site if you need it (tell me which platform).
The problem was that to set the text color prior to calling glutBitmapCharacter, you need to disable GL lighting prior to calling glColor3v (and then re-enable it after the glutBitmapCharacter call). The text has been visible on most platforms for all these years now by luck only, as the default text color would happen to work for whatever video card and OpenGL driver it happened to work on.

i had the same problem on ubuntu after i upgraded to the latest drivers on my ati video card. i could only get proper white labels by switching to an older driver, which wasn't a good solution for other reasons. i switched to an nvidia card and this resolved the issue.

Dear FS experts
When loading a thickness map in FS 4.0.3 for MacOS X Leopard the thickness values of the colour scale bar are not visible because they are printed in black like the background.
How can I change the colour of these mm values from black to white?
Thanks in advance Best regards Juergen
