Thanks for your help on many topics. I just purchased the Saitek radio panel, and with the 777 xp 10.25, it only works with the radio box UN-Checked??? Also, the ACT/STBY button will not work. It did at first, and now, will not work. I am stumped. Any help will be appreciated. I tried to check the Shift F11 radio box, and neither will work. without it checked, I can change the frequency on standby, but not switch it. I can tune it with the saitek, but I must go to the radio stack on the screen and use the mouse to change the active frequency. HELP!
