Just in case, I will detail a little bit what happen:- I launch GameEx from my internal drive- I start to play to a game located on an external drive- After some time, the external harddrive stops- I hit escape's key to quit the game- Screen goes black, external harddrive is trigger and starts- After few seconds, GameEx crash without displaying its interface since the escape key. Tonight, as you say Draco1962, I will look if the problem is not caused by the model of my harddrive or try to find a way to manage it. Thank you,Regards.
