I have just downloaded their mining software (i have not CPU or GPU mined in YEARS)..
I have a VERY old laptop, stuck my wallet addy in, selected low end CPU, Europe pool, on starting 'connecting to Cryponight Algorythm popped up for a millisecond then that just disappeared, then blank ?? Also selected one thread.
Electroneumpoolminer.exe *32 (i have windows 7 64 bit) is running in the background and using 60% CPU power

Anyone got any ideas ?
Thanks

Well do you have a dual core CPU in there? One thread on a dual core would be about 50% CPU power...
