Hello, I'm trying to set up some cockpit actions using a macro pad that has 12 keys and two knobs on it. The knobs actually send button presses, one press for each "click" in a given direction. My intention is to combine button presses on my flight stick with knob turns (and in some cases presses), to manipulate different cockpit dials. For example, Knob2 by itself to select an altitude, with Stick1+Knob2 to select Nav2 frequency. The problem I'm having is that when I set up buttons for these actions (4 total: alt+, alt-, nav2+, nav2-) the button combos for nav2 also activate the solo presses for alt+/1. Is this the intended operation of this feature? Thanks, Derek
