I open a file from folder A in Composer 7.1 and make some changes--add
bullets to a list, change the page color, simple stuff like that. Then
I try to save it into folder B using SAVE AS, to replace an older file
by the same name. Composer says that the file already exists, yada,
yada, I say Yes, replace it and everything seems to be fine. EXCEPT
that the file IS NOT SAVED to folder B.Composer gives no error message
and everything appears fine--but the existing file is NOT overwritten
(and it is not a read-only file).

This is happening on a computer running XP Home and another using XP
Pro. What's wrong here and how do I overcome this?
