As the title says my avionics and lights (so pretty much everything) only works when holding right click on the mouse. It does not matter what panel state I start in either. I've tried cold and dark, APU running, and even T/O config but no luck. Any Ideas? Thank you!

This is a first haha

Could you send a video by chance?

Attached are two videos showing the scenario. One is when it loads in Cold and Dark, and the other is when I load APU ON panel state. The videos are kind of short for file size upload, but it shows the problem. 

Apologies, here is the second senario with APU ON panel state. 

Problem has been resolved! If anyone has this problem here is the answer that worked for me, after further research on the web it turns out other people had the same problem but with other aircraft and the culprit was within the binding conflicts with flight Yokes and Throttle Quadrants. Simply Unbind your master switch or avionics switch from whatever you had binded it too and it should work fine!
