From what I understand, when I send a transaction, the wallet sets a top limit to the gas cost. The default is 121k gas.
How can I increase the max gas cost? One of my transactions (digixDAO crowdsale participation) just got rejected because I didn't attach enough gas. "THE TRANSACTION DIDN'T HAVE ENOUGH GAS TO EXECUTE"
Also, what does it mean when the system says "data can't be executed so it will use all provided gas"?
