Hello,  
  
I've been getting this error:  
PsychEyelinkCallRuntime() Failed to call eyelink runtime callback function PsychEyelinkDispatchCallback [rc = 1]!  
  

This error pops up during Eyelink('CheckRecording') after I made a small change to my code. Before these changes all my code was working and now it isn't anymore. I've changed everything back and it still comes up. Also I am able to run all of the demos.  
  

I'm using a Mac Mini, Matlab 2007b 32-bit and PTB 3.0.10.  

  

Any suggestions would be greatly appreciated.
