Autopilot Hard Time Maintaining ALT/NAV

[cgustafson89 0]

Hello!

I am having a problem with the 747 autopilot.  It swings trying to maintain altitude (up to +/- 1000ft) and the the entered route.  I read of a similar problem with other users but their issue was the use EZDOK and I do not use EZDOK.  Another weird thing about this issue is that I have my yoke disabled with A/P engaged, yet the aircraft responds to my inputs on the yoke with the A/P, LNAV/VNAV engaged.  Anyone else experiencing this and/or thoughts?

Thanks!

So of course I post this and end up fixing my issue right after.  For future reference anyone else, my issue was coming from Sim Physics X.  All I had to do was close it and the problem went away.
