Hello Freesurfer Community,

I am now having issues getting qdec to launch as well. The qdec window pops up momentarily but then disappears. This is the error message I get:

error: xp_attach_gl_context returned: 2

X Error of failed request: 0

Major opcode of failed request: 149 (GLX)

Minor opcode of failed request: 26 (X_GLXMakeContextCurrent)

Serial number of failed request: 1157

Current serial number in output stream: 1157

Could XQuartz somehow be the problem? I am now running XQuartz 2.7.5 on my Mac that`s in Mavericks.

Thank you so much again for all of your help!

Claire
