- I'll reply via email too...

- First, a solution: there is a self-extracting zip file, TIMER.EXE,
- that can be had by anon-ftp from my host, s.psych.uiuc.edu (in /pub I
- think) that incudes a driver that will do this.
-
- Now, can anyone EXPLAIN how this is done? I have always wanted to
- know--it's really not the best situation to have very OS-specific code
- that you cannot understand and thus maintain. And, unfortunately, the
- standard in psych is to time events to the millisecond.
-
- Thanks much.
