Saitek flight panels

I have purchased the radio panel and the autopilot multi control panel. 2 things:

On the radio panel, is there any way to make the other radios active, besides com 1 without having to use the mouse on the screen?

On the autopilot panel, when i switch on auto throttle it doesn't make the switch activate on the screen in some of my stock FSX planes. Any help? Also, when I push the AP button on the panel to activate the auto pilot it doesn't activate on the screen. It actually makes the noise like it is deactivating. I have to switch on the button on the screen and then use the panel. Any help???

Thanks
