I saw an earlier post about this from feb, and the hope seemed to be that it would be fixed with a new pull fro eyelink.  I recently downloaded the latest from them and psych toolbox and I am still getting the issue.  When setting a custom calibration, the dots appear off the stimulus screen, and outside of the box that represents the screen on the eye tracker computer.  Otherwise everything else seems to be working fine. We need to do this because the top corners of our stimuli are cut off to due the circular bore of our MRI magnet.
