A personal problem but may be of interest to others. My mouse, a Logitech G602, won't perform the wheel functions for turning on the Garmins, the two rotating light controls and the pitch bar on the AH. If I right click the 'c' on the Garmins, they come on but are dim - clicking the radio lgt control brightens them. Both light controls pop out with clicks but the panel/pedestal does nothing else. The spot on the Artificial Horizon, to adjust the pitch bar up or down, does nothing. As I said, an apparent mouse problem though it works fine otherwise.
