I am clueless, actually, but the first things I might look for would be 
(a) does the script exit? and (b) is the script waiting for some input?  
Can you put some debugging lines in the script, say to print to a file 
(place markers, variable values, whatever) that could be read after the 
event?
Hope that helps
