We reorganized some of the URLs in Gateway, so as long as this problem does not persist I think it's expected.
Hmmm. We haven't seen that ourselves, but it sounds like the initial load of the Klingon assets (pictures and so on) is slow for you. Once they load up, it redraws correctly. We'll take a look at that; I wouldn't expect then to load slowly.
I just tried it myself - the same thing happened. It was only for a split second, but other than the length it was exactly as psiameese described.
