I've been fighting the setup for over an hour. Near as I can tell I have n1mm+ configured according to the docs. Still, I can't get it to use mmtty or 2tone. The only DI window that comes up is mmvari. There is no option in Window->Digital Interface that allows me to select a DI window. I've rebooted and still no joy. 64 bit Windows 7. Lee (N0SQ)
