eprime Go bug

Hi

It seems  that an eprime go experiment that works well on E-run, doesn't function at all on eprime go : the mouse is missing. this is also the case for the samples found on PSTNET support (curious).Since there is no manual delivered with eprime go, it s a bit complicated to understand what's going wrong.I had the same problem with the keyboard. I had to declare the keyboard in the first line of experiment setting. But I can't do this for the mouse in case of crash to allow to stop the experiment . Any ideas? thanks
