MindView pour Mac

[Ignimbrites]

J'utilise MindView sur mon MacBook Air et ça marche bien. Mais lorsque je réalise une carte et je l'envoie à un collègue qui utilise un PC, toute la mise en forme disparait mais le contenu reste conservé. Ce problème je le rencontre également lorsque le collègue m'envoie son document. De même, je ne peux pas envoyer ma carte par mail car à chaque fois que je l'envoi je reçois ce message d'alerte :
Delivery of the email was stopped!

The message has been blocked because it contains a component
(as a MIME part or nested within) with declared name
or MIME type or contents type violating our access policy.

To transfer contents that may be considered risky or unwanted
by site policies, or simply too large for mailing, please consider
publishing your content on the web, and only sending an URL of the
document to the recipient.

Depending on the recipient and sender site policies, with a little
effort it might still be possible to send any contents (including
viruses) using one of the following methods:

- encrypted using pgp, gpg or other encryption methods;

- wrapped in a password-protected or scrambled container or archive
(e.g.: zip -e, arj -g, arc g, rar -p, or other methods)

Note that if the contents is not intended to be secret, the
encryption key or password may be included in the same message
for recipient's convenience.

We are sorry for inconvenience if the contents was not malicious.

The purpose of these restrictions is to cut the most common propagation
methods used by viruses and other malware. These often exploit automatic
mechanisms and security holes in more popular mail readers (Microsoft
mail readers and browsers are a common target). By requiring an explicit
and decisive action from the recipient to decode mail, the danger of
automatic malware propagation is largely reduced.

Merci de m'aider à résoudre ces deux problèmes
