David, as always, thank you for your helpful suggestions.

<br>stimulus, this will almost never be exact, and is in any case
<br>superfluous. Suppose your text stimulus is named StimText. Then
<br>StimText.OnsetTime already tells you the onset time of the stimulus,
<br>you should use that (see
<br><a href="http://groups.google.com/group/e-prime/browse_thread/thread/39e899d3457d4917" target="_blank">http://groups.google.com/<wbr>group/e-prime/browse_thread/<wbr>thread/39e899d3457d4917</a> ).
<br>
<br>If you think further, you might not even need to do that. If you
<br>have StimText start after the key is pressed down, and have StimText
<br>launch its own "release" input mask, then StimText.RT will already be
<br>the appropriate RT for the release response relative to the onset of StimText.
