@Asessa: others seem to have the backlight working correctly with cockpitsonic modules and latest updateed version?
Regarding the radio spacing, if you want to use 8.33kHz spacing, in your FMGS server\PERF\PA320\aircraft.ini look for the Spacing833 line and change it to
Spacing833=yes
or add the line if it does not exist.
@Netserv: maybe graphics card drivers? ATI or nvidia chipset?
