ido-mode and saving attachments

Hi,

When I enable ido.el (which is part of Emacs) in my init.el with

(ido-mode 'both)
(ido-everywhere) 

it can't handle saving attachments.  It saves the attachment with the file name
that's on top of the completion list, prompting you to overwrite it; and it
won't save in the directory that you choose with the ido prompt.  If I comment
out ido-everywhere and use only

(ido-mode 'both)

then I get the expected behavior, but ido does not work for attachment saving.

Is there any way to get ido work with WL?

Note: I'm using mime-preview-extract-current-entity
(https://www.emacswiki.org/emacs/WlFaq#toc43) to save attachments.  But I can't
see anything in its definition that would cause the problem.

All the best,
Greg
