Thanks Mr. Ripley.
I'm using the Mac usb keyboard that came with the iMac some years ago. I'll try another if I can come across one.
I'm so close....Key mapping, 75% of the views and all three axis (including the twist stick I sometimes use) seem to be functioning fine.
I'm also noticing framerate issues in a busy battle. I'm afraid the obstacles to remaining in AH are mounting.
