Minor correction here, you can use "abc" but not "d"

This poses a problem, if you have a 13GPU rig, and use altnum -1 or altnum -3
 to change from first GPU=0 to first GPU=1
You loose the ability in the console to toggle GPU 13 off/on, (you can still do this in ethman of course).

Small bug for Mr Claymore.

Happy mining everyone.
