Had a problem last year where every time I tried to manage speed, after about 3 seconds it would revert back to selected speed. Rather that than the other way round!
Vertical profile after an altitude constraint - in DES mode the aircraft will continue to descend on the profile calculated prior to the constraint even after it has passed it. A quick DIR TO will cure this before you end up 5000ft low.
