Eyelink Toolbox - Occasional crashes after transferring EDF file

[craig_wilson_btm]

Greetings,

The lab I work in has been experiencing crashes on two different G4s
running the Eyelink toolbox for OS9, when the experiment transfers the
EDF file from the Eyetracker PC to the G4.

The snippet of code where the crash occurs is:

% Copy EDF file from Host computer to other directory for further
analysis.
status = eyelink('ReceiveFile', edfName, edfName, []);
if (status < -1)
fprintf('Error transferring EDF file to local directory!');
end

where edfName is a string containing the name to use when saving the
file locally.

The behaviour observed during a crash is the blue transfer bar will
appear in the top - left corner of the screen to indicate that the
file is being transferred, however at the end of the transfer the
computer will lock, and has to be reset via the power button.

The versions of the components used for the experiment are:
OS 9.2.2
Matlab 5.2.1.1421
Eyelink Toolbox 1.4.4

If anyone else here can offer assistance as to a workaround, or cause
of the problem that would be greatly appreciated.

Thanks,
