Okay. I installed the CS707 and CIVA-INS into FSX-SE, and so far it sort of works! :-/

The CS707 is causing problems in FSX-SE. Pressing SHIFT+2, 3, etc. and nothing happens, no 2D panels show up, so I have to use the menu to access them. Pressing SHIFT+Z turns the AP on & off, yet it should display some text (including the longitude and latitude coordinates) at the top of the screen!

The CIVA-INS turns on and works, but it only aligns sometimes, so I'm having a lot of fun - NOT - trying to fly the CS707 in FSX-SE. :(

I will uninstall/reinstall the CS707 to see if I can sort it out, otherwise I'll have to wait until it gets updated for FSX-SE.
