I turned Sim Physics X off and the issue still occurs.
No I don't have hardware trim axis assigned, but I do have the trim set up on my Saitek Yoke on the 2 way rocket switch if thats what you mean?
I do have the beta and I had a look on the Hifi forum and read about this issue. I turned ASN off and it still didn't seem to fix the issue. But i didn't reset the sim after I exited ASN. So maybe thats why it didn't seem to do anything?
I have uninstalled PMDG777 and I'll try to install a fresh copy and see if the issue still occurs.
thanks
