No problems at all for me on the 757 4.4 update. The landing lights behavior is weird but workable. For me this is been the best update for the 757 by far. Mark

So have you been able to get the autopilot to take over speed management when VNAV is engaged?  Usually, when VNAV is engaged and in control of the aircraft speed, the speed window on the MCP goes blank and the autopilot adjusts the aircraft speed according to the VNAV profile in the FMC.  I have been unable to get this to happen with this version.
