EDIT ######I might have got it############# Instead of using the throttle TOAG button, I used the continuous thust button on the glareshield right below the AT arm switches.  This time it did what I wanted it to do.   I also changes my cost factor to 500 from 100, and it seems to have stopped altering my legs page after takeoff. What does everyone else use for cost factor? ****EDIT #2 ******************!!!!! It only switches from TOGA mode to VNAV Speed hold mode if LNAV is also selected!!   AHA!!  I knew I was missing something.  If I only have VNAV selected, it never gets out of TOGA mode.   That's a major bug, I think.   You shoukd be able to use heading mode to hold the runway heading until ATC turns you.  But if you use heading mode for lateral guidance and have VNAV selected for vertical guidance, it fails to follow the 250 k speed restriction.  As soon as I hit LNAV, the VNAV starts working properly!

I have said that about the LNAV and VNAV in an earlier post. I'm not sure if my post was in this topic, or not. :(

Have you tried it with the TO/GA button on the Throttle since you discovered that? It should work the same as the Climb/Continuous (CLB/CON) Thrust Switch.
