When you press ALT+F3 to save the autotext entry, by default Word 2007 wants to put the entry in the QuickParts gallery of Building Blocks.dotx
Click the dropdown adjacent to Gallery and select Autotext and similarly click the dropdown agains Save In and select Normal.dotm. Then OK.
Depending on whether you have Word configured to automatically save the normal template on Close, you may get a prompt to save the template when you close Word. That autotext entry will remain unless Word is closed without saving the template.
