Hi again,<br><br>I have been encountering an error when attempting to use either tksurfer or tkmedit via VNC on a local server.  Here is the output whenever I type tkmedit or tksurfer:<br><br>GLUT: Fatal Error in tkmedit.bin: OpenGL GLX extension not supported by display: 1.0<br>
<br>I looked through the threads regarding this problem, but still have been unable to find a solution.  The output of &#39;cat /etc/redhat-release&#39; is Red Hat Enterprise Linux WS release r (Nahant Update 7) and here is the output from the command ldd `which tkmedit.bin`:<br>
