Auto-text on MS word

Does anyone know why M/S didn't have it on vista like it used to be on the other MSWord? And have they seen sense and put it on the next one.
It is on Vista but it doesn't work the same. For instance instead of having a little box comeup with the word that you've put in the auto-text set up box for you to add by pressing enter you have to go in to word options and then put it in auto correct and it doesn't bring the box with the word in up and you don't press enter... you press the space bar!!
