Basically, we think this may be a result of the NAI quarantine of MS-Office
related executables (among others) which occured to many over last weekend.
A repair install of Office 2000 was performed, but did not resolve this
issue. The email with the issue was originally composed by the sender using
"Paste Special" and then selecting "Embedded Excel". Changing the email
editor from RTF to Word (with or without HTML) doesn't resolve. The email
will forward if forwarded from the email list and not from the opened mail,
which does open an editor, but when the email is opened and then forwarded,
the original email closes and no new editor is opened.

Any ideas?
