I downloaded the latest bitminter client on my mac and it opens up all the way but there isn't a window that opens.  It is open in my dock and all the menus show up at the top of the screen but the actual window is no where to be found.  I've tried right clicking on the icon in my dock and "showing all windows" but that doesn't bring anything up either.  I've run the bitminter client on this computer before and it's worked perfectly but it's been a while.  Any suggestions???

The Bitminter client is not recognizing my ASICMiner Erupter. I restarted the Bitminter client several times and it is not finding the Erupter. What can I do?

Is it possible to run this miner on a Mac? How do I download it? I apologize for asking such silly questions. I am definitely a noob when it comes to cryptocurrencies.

I got some newbie questions:

• What are "workers"? I only have one. Would it be better to have more? How would i get more?
• What's the difference between namecoins and bitcoins?
