Hi all,  
  
Here are important installation instructions for the OS X Psychtoolbox   
version 0.8, announced earlier today.  
  
1- Remove any path settings into previous versions of the Psychtoolbox.   
 Set the MATLAB path to include the Psychtoolbox folder and all   
subfolders.  
2- From the OS X terminal, run the script   
Psychtoolbox/PsychContributed/simplepsychtoolboxsetup.sh. Calling   
KillUpdateProcess from the MATLAB command line will open a terminal   
window and give detailed instructions for how to do that.  
  
The demos were meant to give the instructions in step 2, which they do,   
but I overlooked that those instructions would be occluded by the   
onscreen windows which the demos open. I'll fix this in future   
versions by having KillUpdateProcess not only give instructions, but   
also close any opened onscreen windows.  
  
best,  
  
Allen  
  
ps Thanks to Keith Schneider for the feedback.
