"attachment" mistake on TB 10 / Mac Rated 5 out of 5 stars

I use Stationary since many years. Great AddOn! ...unfortunatly, since last TB update (10.0.2) I get an error. It works fine when I start writing a mail with my stationary. All images from the template are in the Mail.

but when I like to send the mail, the images in the template can't be found anymore.
When I just pull a pictrue from desktop into the mail, it works. Any idea?

This review is for a previous version of the add-on (0.7.8). 

It is known TB 10 bug.

Basically, to make Your mail work again, remove all links with "skype:" or "tel:" or similar.
