I met a stange problem of documentmap: the font in the document is too large.
I checked the font style of documentmap, it is normal: 10.5 pound. I think it
is because the view percent of documentmap is too large(maybe 500%). But I
never found there are anything about view percent of documentmap! I
uninstalled Office XP and install again, it remains as before. So, what I can
do?
