e prime crashes if subject presses response button twice

[Hester Duffy]

It may be to do with the way your program deals with responses; I've dealt
with an issue in the past where, if the response wasn't what e-prime was
expecting, it fell into an interminable loop and then crashed. Is E-prime
doing anything with your responses other than simply recording them? For
example, is it using them to set event codes, to determine feedback, to
choose the next stimulus, anything of that sort? If so, it's worth having a
look at the bit of code that does that, and ensuring that there's a
catch-all "ELSE" function, so that if the feedback is something other than
what e-prime was expecting, it still knows what to do with it.
