Same problem here.
Funny thing is that I had dual or tripple logged (for item banks and transfers) and this problem only happened on my main (paid) account.
Froobs were all the time logged and OK (no LD) and as I was on team speak all the time I am 99% sure that it is not my internet conection.
One more thing I noticed there was sometime quite long delay (10-15 sec) between the moment I logged on (with all graphics so I could stand up and start running) and moment I saw anything in any of my chat windows (bots, org msg, and other general spam)
