I have a bug or issue with the overhead panel switches, generally the electrical: windshield heat, pitot tube heat and sometimes the electrical generator on/off switches.

When using Shift + A to bring up the panel and I set the switches to ON and then use F9 to go back to the VC all the switches then revert to the OFF position. If I select them again in VC mode they stay ON but not always, sometimes when a quick check before take-off will reveal some have turned themselves OFF again, very annoying.

Same with the fuel heat, turn it ON it goes on, look again and it has gone OFF.
