Hello,  
 I am interested in the timing accuracy and timing resolution in the  
Windows version of Psychophysics Toolbox. I looked around the web  
site briefly, but did not see any timing tests/results. Also, I was  
wondering how you enforce the timing? Is it through some Matlab  
functionality, or did you have to use specific Windows function calls  
to do it? Any information would be greatly appreciated.  
 Thanks,  
 Trina
