I do not know the situation on that aspect, as the funds are not held with MtGox (we are merely helping with the investigation and trying to ensure the information flows correctly to the community).
It's been stated elsewhere on the board that MtGox has now frozen the Bitcoinica MtGox account. Can you confirm whether that's the case (it would be a reasonable action to take, but users generally tend to disbelieve such claims as I'm sure you're aware from having to explain such situations in relation to your own financial institutions)?
