Does anybody else have the problem of disappearing logIn buttons or even disappearing account control buttons? When that happens, and it happens quite a lot, the area where these controls should be is just empty. The bar next to the ginormous new oppo symbol where the recently hashtagged posts are shown disappears as well, and I can't see replies to posts no matter what. Apart from that the site acts normal.The only way to get these controls back is to refresh the page in all shapes and forms possible for ages and pray/sacrifice a goat. This happens about 2/3rds of the time and in Opera and IE. Any experiences, ideas, condolences?
