BUMPDid a clean install and PMDG MD11 + CH drivers as suggested, still the Autobrakes system remains engaged. Still no solution yet? Running W7-64 now with FS2004.1.
Just wanted to share what I just found and what you might already know, this bird is awesome: in the loadmanager I just switched to the widescreen panel and it makes a whole lot of difference even in 1280x800! Many thanks for this awesome bird!
