Smarttags in Word, recognized when?

[Jochen]

Hi,
when are Smarttags recognized in Word 2003? With me Smarttags in documents
saved by others (Smarttags are not saved embeded) are recognized only when I
type something. And then Smarttags are only recognized in this chapter where
I changed something. Of course it is possible to start recognizing manually
by clicking the button "check document" on the smarttag-register but this is
not what I want. Isn't it possible to recognize Smarttags when opening a
document? Are there any concrete documentations from Microsoft available?

Thanks
Jochen
