Is it just on my computer, or for everyone else... those boxes that used to pop up over people's usernames and on items- they won't show anymore?

Hold the mouse a few seconds over an item. There are new boxes and currently they take some seconds to load. Only a small loading bar shows up first.

Actually many people are having problems with the boxes -some don't show at all anymore, some only get partial information, like just the name of the items, others get the correct box, but with missing pieces of info. If you have an older computer, and older operating system, and you don't or can't use the very most recently updated version of your browser you are likely to have problems. Your security settings may also now interfere. Also, from what I'm told about how long the box takes to load, the fact that you can only load it once and other issues, I'm not going to bother even trying to get my system to view them, just not worth the benefit anymore. I will miss them, but what can you do.
