It's not recommended that you alt tab/alt esc switch from a full screen, although I usually don't have any problems with it, it can cause problems. Use windowed screen or another computer next to the primary one if you need to close fsx regularly during flights, much better.Does it happen everytime?

A couple of tips... when you return to the 747 immediately check thrust status, usually a press of the VNAV key (even tho it is lit) will keep things running smoothly. You can also pause before switching apps but I usually am lucky enough to only need to reset VNAV.
