'Pygaze_trackertest' doesn't work correctly.
I get errors of pygaze (0.6.0) in MacOS using Eyelink1000plus.
When I started 'Pygaze_trackertest.py' of the examples, it caused two errors.
[Calibration and Validation errors]
As I did the calibration and validation, it started but didn't presented a black fixation at the displayPC. The monitor of displayPC kept a gray blank and I was not able to see the black fixation, while the hostPC showed the screens of calibration and validation correctly (actually record the eye movements).

[Can't end the file]
I was not able to end. When I pressed 'esc' and 'y' to end, it froze. I had to do the forced termination.
What is cause?
