I'm using a Dell Latitude E4510 with Windows 7. I was able to play the first two episodes without any problems. With Episode 3 and 4 I had the Flux Capacitor at the botton corner loading and then crashing with sound and the message "video driver has stopped responding and was recovered". After I searched this forum, someone posted a prefs.prop that used the minimum hardware and it worked fine (I was able to change prefs and adjust it without problems). With Episode 5, same problem, but this prefs.prop from Episode 4 does not work at all.
