[VM] deleting saved attachments

[Julian Bradfield]

If I save an attachment, which I routinely do via C-c C-s, and then
later I delete it (with $ d  on the button), instead of just deleting the
attachment, I lose a large chunk (probably corresponding to the size
of the external file) of the actual folder.

I must be the only one seeing this, otherwise there'd have been
complaints - but I'm not aware of doing anything that would interfere
with any of that code. Should I look harder, or is it possible there's
an XEmacs interaction?
