Well, I'm still having the problems that I outlined above. I'm running Windows 8.1 on an HP Laptop. The intro sequence seems to run perfectly. All the keys seem to function OK - I can navigate all round (using both the WASD keys and the arrow keys) and I can take photos, but I CAN'T use the ESC key or the BackTab key to bring up the menu. That means I can't do a Save/Load or adjust the settings in-game. The only way out is to Alt/Tab back to Windows and kill the Obduction session. The other problem is that, having navigated the Intro and been hit by the yellow flash (with the 'Obduction' title), it just stays for ever in that scene with all the yellow fragments.....there doesn't seem any way to move the game forward to the next scene, so I have to cancel out. I've tried de-installing and re-installing the software but it's exactly the same.

Very frustrating!! Grateful for any help please.
