Did the latest install from https://github.com/ethereum/webthree-umbrella/releases
. Ethminer seems to run ok, but I was curious to see Alethone in action. When I try to fire it up I get no gui. All I see is the process running and my cpu usage going through the roof. What am I doing wrong? Also, I heard Alethone only supports mining from a single gpu - is this the case?
