You may try of the following methods:

a) RECOMMENDED if it works. Set the duration property of your StimObjecto to 0 
and the response time limit to some appropriate time (infinite would be 
better). Then use the run method, do whatever you want (trigger the pulse, ...) 
and write a code similar to the following in order to wait for the response.
do while StimObject.RT <> 0
loop

After that, you can proceed.

b) If the previous method doesn't do the trick then use a wait object with 0 ms 
duration and appropriate response settings (including time limit). You would 
present this object before the inline. Then you would use the draw method for 
your StimObject and get the response from the wait object. Use a similar loop 
as in the previous method to wait for the response:
do while WaitObject.RT <> 0
loop

Hope this helps
