I initiated a withdrawal of 1.25 bitcoins from bitstamp last night.  This morning when I checked my account I found that the withdrawal was supposedly successful (although none were delivered to my wallet) but it was followed by a supposed deposit for the same amount a short time later. 

So fortunately nothing was lost but I wasn't able to withdraw my bitcoins.  I opened a ticket with them this morning but no word yet. 

Has anyone else had this happen?
