I am trying to deposit some Bitcoin into my MtGox account. When I input the amount, and press enter, message comes up
"One last Step!"
"Send (amount here) Bitcoin to this address":
and nothing to confirm it, no box to check OK or ENTER nothing, just that box telling me "one last step". What step?
Copy the address given, then paste it into your Bitcoin program and send the bitcoins. After a few confirmations, the Bitcoins will be visible in your Mt. Gox account.
I have done this several times, never had any problems.
