Hi Kirk,
I'm using OSX 10.11.1 and Photo Mechanic 5.0 (16765).
This evening I was sending a set of pictures out to several media outlets and ran into a problem while emailing pictures from within PM.
I selected a group of six pictures and sent them via email. I have configured the settings in the 'Send Photos Via Email' window so that a separate email is created for each image - and the images are not reviewed in Mail.
When I clicked send Mail opened and new emails were created and sent straight away. I checked what I'd sent later that evening and the six emails were in my sent box - but not one of them had any images attached.
This is the same setup I've always used and have never had a problem. Any ideas what's wrong?
