I withdrew 3.82761346 BTC from MTGOX to BIPS address 1PrCvhnTVqc6C9VcsWibPYTeQHyLrFJGEb on November 6th.

Then Spent .861 BTC sending it to 1CK8gvdupixuWWsPxo2dZLtXqZkVaYkhwA on the same day it was deposited.

My balance when BIPS went down should have been 2.96661346 (might have included the .001 fee)

Can you give me a crash course in understanding tracing the transactions?
