Stockfish not loading?

In analysis mode the engine on top doesn't seem to load properly anymore. The usual automatic game analysis works fine as always, but the engine on top that looks at the current move and suggests best move with a grey arrow isn't starting. It's been like this a couple of days, at least for me, so thought I'd report it.

Thanks for a great site!

i am seeing a similar issue. My engine is stuck after move #5.

PNaCl? What happens if you refresh the page?
