lol login at work using my phone as a tether so I know what you mean by slow. I have not noticed mine showing all as done, but I tend to walk away for a few min while it loads :)
I'm sure it's something to go with how updated your browser / flash is. When I browse at work, all my skills are coloured in with the ones I've learnt having a little green tick in them. At home, however, it's the same except that skills I haven't yet learnt are shaded out.
