I followed your steps and it didn't crash for me. Maybe a Win 8 or Win 8 driver issue ??
Could be, but considering it is Construct 2 itself that crashes, I don't think it is driver related.
Oops, you're right - should be fixed for the next build. (Some help links appear when you right click in that dialog.)
Indeed they do, but right clicking on an object itself is... I dunno, not frequent?
Either way, glad it is not one of those pesky "it only happens to me" things.
