still a blank prompt
It works like bitcoind, you'll have to open up a command line and send commands to it to check what's it doing, the executable's prompt will remain blank. You could also check if there's any trace of a blockchain in "%appdata%/mincoin". In my case, it's indeed connected to... some network, and downloading blocks. In fact, I mined a few, but they were all stales, according to the debug.log.

ERROR: BitcoinMiner : generated block is stale
I'll just poke this around for a while longer, then I'll just go back to mining Litecoins.
EDIT: Finally generated a valid block. Though, I'd still probably check the code thoroughly and compile from source, instead of using some random executable in a .zip file :p
