I'm using coingrabr to CPU mine
BTC with an old PC and it works great.

Glad you're getting some profits from your old hardware, thanks for the payment proof, please PM me with your FH username.
how to prevent command bar from making more windows when miner is running
Not really sure what you're referring to here? Could you go into a little further detail, we shouldn't have tabs blowing up all over the place.
Hello
I have a question about this site, because every now and then there are changes on it and whether this site is fair enough to pay to others, because the payment you made is a payment to your personal account and how much on the recently launched website is a lot of them, but different values. How can I be sure that I will receive a payment, and why is it on the Balance page (satoshi) if it is calculated differently, which does not have a real dimension, between the two. Or maybe you are the owner of a similar site, please explain my uncertainty to me. Please ?!

We are openly transparent with all of our transfers and payments, you're able to see out payout rates in full transparency at the below URL.
https://faucethub.io/faucets/BTC once you're on there you should be able to search for "CoinGrabr" and see all of our activities through the FaucetHub API which includes payments.
Unfortunately, the bonus is on your first withdraw, however whenever you post a payout screenshot on here, I'll swing you a little something, something, just give me a heads up that you've posted a screenshot.
