Hello I am a newbie when it comes to Ethereum. I recently installed AlethZero client on Windows 7 (downloaded Ethereum-win64-latest.exe from somewhere) and tried my hand at mining for a while. Made around 200 ether.
I want to know my account number so that I can confirm if the whole thing is actually working. Cant figure it from the AlethZero GUI. Maybe I am just too dumb for this... I need help

I am attaching a screenshot of my AlethZero client and the associated .json file. Someone please tell me how to get the damn account number/ account address.

I installed a newer version of Ethereum client and then your double click trick worked.
XE871F14LGYL8THRWY1JXD13MF3YHXREWE (00564b9d3de20878c04c6c7012c83a03f8f8092e) is what I got.
My last question is how do i verify the ether balance in my account '00564b9d3de20878c04c6c7012c83a03f8f8092e'?
Even though the AlethZero client shows positive ether balance in the account, when I try to check the same in geth, I get zero balance. I use the following command:
eth.getBalance("0x00564b9d3de20878c04c6c7012c83a03f8f8092e")
Am I actually mining anything or am I just wasting my time?

I was playing around with the client and I hit 'Prepare next DAG' and all the ether vanished lol
I don't get it... What did I do wrong? Any ideas??
