I did a small investigation some time ago to see how widespread the problem was, and these were the results:
- Sent 0.001 BTC to an address generated with a password you will find in any top 10 common password list. Taken immediately. - Sent 0.001 BTC to an address generated with a six digit password. Taken immediately. - Sent 0.001 BTC to an address generated with the same six digit password as above, but with Point Conversion set to "Compressed". Untouched. - Sent 0.001 BTC to an address generated with an upper/lower/digit six character randomly generated password, normal Point Conversion. Untouched.
Someone is definitely out there grabbing things from weak-passworded wallets, but even a six-character random password thwarts them.
Edit: Mechs, tell us which password you used. It's already compromised, so there should be no harm in revealing it. If you can't reveal it because you use that password in multiple places then guess what - that's how they got your password in the first place - by stealing it from some other place you used it.

95 chips. That'd be 315.789473684211MH/s per.
Does this mean you need to put 95 of those chips in a single device to get the hash-rate that a bfl little single (30Gh/s) is supposed to give? I don't see why this is a problem. As long as the cost and power consumption of the device is reasonable, who cares how many chips it has?

How are you going to solve the problem that everyone in possession of the coin could "empty" it, leaving it useless? Unless the QR code is the public key, in that case - where is the private key?

I did a check of the fake 137571 block, and the only transaction that's there, but not in the real 137571-137573 blocks is the generation one. Which is what you'd expect from a "legit" dupe block. Looking through the other one now. edit: Same with the 136755 block. Only generation block is missing.

That money went out of the address doesn't mean anything. Any money sent into mtgox gets pooled together, so if someone took out your 50.56 it would most likely not come out of the same address you used to add it. I suggest you try the support forum on mtgox too.

Post a screenshot of the program running. (with details like addresses blurred, if you feel like it)
It's running, trust me. I'm more interested in the number of connections and block count you have in it.
