where to report bugs? repeatable Word XP printing bug

[Hd Wu]

Hi,

The Word in Office XP behaves very strangely: for some of
myself-created documents, changing "hide/unhide edit
marks" option would cause only part of pages to be see-
able in one of the the two status. And only the pages that
are see-able in both status can be printed out.

I believe this is a bug, but don't where to send my
document so that the bug can be fixed.

Thanks
