wait to collect response

Hello,

I have an experiment that runs some audio files and I’m having an
issue somewhat similar to what was discussed in this post:

http://groups.google.com/group/e-prime/browse_thread/thread/9d6274c8e8c69d6e/270bd8208b9e1d81?lnk=gst&q=wait+to+collect+response+#270bd8208b9e1d81

The experiment that I have runs audio files that are approximately
5500ms in length and the event that a participant needs to respond to
occurs at 4800ms. I wrote some script to adjust the real reaction time
from the RT of the object which works fine.

I also have the audio object set to terminate after a participant has
made a response thus moving them to the next trial.

The issue with the program is that if a participant responds prior to
the 4800 mark, the program jumps to the next trial. Turning the
objects  end action to “none” doesn’t help because if a participant
responds prior to the 4800 mark, the RT collected is not for the event
under study.

My question is, is there a way to hold off on collecting a response
for an allotted amount of time to an object?
