Eyelink Toolbox question and request: Anti-saccade task

1
So, I'm about to sit down and start programming up a standard anti-saccade task for a class demonstration and eventual experimentation and I thought, Hey, perhaps someone has already done this and is willing to share??? Any takers?

Barring that, I have two questions.

1. Why when I run the EyelinkExample.m script, I cannot see the eyes and head markers as I can when I run a standard c-script from Eyelink?

2. Why when I do a calibration within the PsychToolbox, I get many more "errors" and generally poorer calibration when when I do this with the programs supplied by SR research?

That's it for now, but I'm sure that there will be more questions as I dive into this new aspect of PsychToolbox programming.
