E.s.e. I remember discussing same problem via email with other person recently. It also was about the fact that on one of laptops boxes were displayed with solid lines for not-assigned faces, insltead of dashed. This is not correct, it should look something like this instead:
However, this is very strange and rare bug. For majority of users everything looks fine, but apparentely not for everyone. Unfortunately, I cannot reproduce this behaviour on any of our testing PC’s. It would really help if you could give any hint why this particular laptop is so special.
