Does anyone else with v4.4 have trouble with the autothrottle speed management when VNAV is engaged?  On my first flight, I had programmed a flight plan in the FMC, I engaged the flight directors, autothrottle, LNAV, VNAV, autopilot CMD, and the autopilot did not take over the speed of the aircraft.  Usually with VNAV engaged, the speed window of the autopilot is blank and speed is managed by the aircraft, but I had to manually enter speed values during this flight.

I submitted a ticket, #4617, regarding this issue.
