Sigh. This is why that checkbox needs to be removed (and will be in the next client version). If we have a big button that says "Generate coins" can we really blame people for thinking it will generate coins?
knigt12374: Don't try to mine by using the "Generate coins" option built into the client---it's little more than a historical relic at this point. You will probably never generate a single block using a typical CPU (there's a 50% chance you'll do so within 65 years). To have any hope you need specialized hardware (most commonly a high-end video card) and software (for example Kiv's GUI miner
, and even then you should probably join a pool (for example BTCMine
to even out the variance.
Try reading the FAQ
