Hello,I am sorry if this has been covered, but my searches yielded no results, perhaps because i wouldn't know what to put in the search field anyway.today while flying online from OAK - PHL in the 737-700 2D only, all was going fine until about the time to start my descent. When i went to the overhead to turn on the fasten-seatbelt i noticed EVERY switch in the overhead had been flipped the other way. Even the battery switches and everything had been flipped to the open and off position. And the switches in groups, i.e. fuel pumps or hydraulic switches, when i would click one, they would all turn back on. but the GEN 1 & 2 switches, while i had engines on (obviously because i am flying) the lights were illuminated bu i couldn't flip those to draw electrical power from the engines. I had to start the APU and use it as a means of electrical power. I tried shutting an engine down in flight, restarting to see if then i could transfer power. the switch wouldn't move. so when i landed i shut everything down like normal, and tried restarting the engines like i would a t the start of a flight. GEN switches wouldn't move. so i simply selected new aircraft from the menu, PMDG 737 2D only, and all worked fine. Any ideas??Thanks,Darren

this happened to me before, but only when I messed with the panel light switches in the overhead. I assigned a key command to the dome light and havent had the problem since
