I have 2 Skyview HDX 10" screens in my RV-7A and both, though especially the left one, is really slow in registering when I push one of the buttons on the bezel. Sometimes it will register it when I click it again and flash the screen I want and then cancel it out and sometimes it takes a few pushes for it to open what I want. Very frustrating! Even sitting in the hangar when I update the database the 7&8 buttons, one or both, won't hold long enough to go into the menu system for a few minutes. It's been doing this since shortly after I had them installed. Can anyone help me with a fix?
