Hi.
I dont have P3Dv4 i use FSXA , but when you said the canopy opened then closed by itself , was you on the ground at an airport , if so you may have been in the range of the refuel spot , this is a known sim problem that effects all the sims.
Has for the klick spot not opening the canopy , this has happened to me in FSXA , and happens when you accidently hit the closed mouse button twice , i find in FSXA , if you HIT SHIFT+E the canopy moves , sometimes from open to close , then the clickspots to open/close canopy start working again.
Has for the head phone cable showing but plug not showing , are you changing the view zoom or is it default zoom or are you useing trackIR or VR headset , as i have not had this issue in FSXA.
regards alan.
