Has another fork occurred? Coinchoose is quoting Erundook's pool with difficulty of 1.2, while Vern shows 1.5. Been this way for a few hours. Last time this happened was because of fork.
It does look like another fork
My client is on block 56732 as well as multipool.in as well as
http://bot.webboise.com:2760/http://www.bottlecapspool.com/ and cryptsy are on block 56,757.
I guess the problems which caused the last fork were never fixed inside 1.4 client
