Hi, everyone,  
  
I tried to compile DriftDemo from psychtoolbox. After the   
compilation, the stand-alone executable file was sucessfully created.  
  
but... when i run it, the whole screen went black and grey (flashing   
couple times) for about 5 seconds. I can't see the sinewave (motion   
pattern) at all.   
  
It supposed to show the sinewave motion if I used matlab to run the   
driftdemo.m  
  
Does everyone know how to solve this problem??  
  
Thank you so much.
