Hello I`m having exactly the same problem as yours. I tried adding the line DisablePreload=1 to main heading of FSX.CFG and it did work only for once, but when i tried again i had the same problem again.I know this sounds so strange, but still cant figure out why!is there anything else u done? this is really annoying after spending around 40 min doing pre briefing... i would really appreciate ur help guysKind RegardsSenan Zubi

Hello Senan,Try deleting your FSX.cfg file to start fresh and clear your settings.It'll rebuild when you load FSX again.Cheers,Bryan

Hello Bryan,I will try that now and let you know, Beside I noticed that if i do -Not the First Officer- the Engine start everything goes normal and works fine. But if i let the First Officer do the BS-Before Start- and ES-Enigne Start- that problem shows up again.Kind RegardsSenan

The dissable preload was not the fix. I absolutely unequivably resolved this issue by disconnecting my GoFlight controls. I never put any diagnoses into attempting to identify which or what specific control or driver within GoFlight was causing the issue or conflict within PMDG. I was running GF-45, GF-MCP, GF-P8, GF-TQ, GF-LGT, and GF-T8 panels with the latest GF driver. I simply unplugged the batch of them uninstalled the driver and never looked back.I still use CH pedals and yoke no issues.

Gary,Thanks for the tip.Cheers,Bryan
