using old task on new computers

[David McFarlane]

BTW, if you care at all about critical timing, then you must, repeat 
MUST, also thouroughly study chapter 3 of the User's Guide that came 
with E-Prime.  You should also at least run the RefreshClockTest 
program (downloadable from PST) on every subject running machine, .
