PSE 11. I have the same problem. I cannot write a message when I forward photos. PSE 9 works fine because before you send there is a box to write a message. Because PSE 11 mail is so bad I am using PSE 9. My solution which I don't like is this.
I send the photos to myself. Then I forward the photos to the person I really want to receive them. This allows me to write a message. Adobe should fix this immediately. Note: it is also impossible to change the print size or select the type you desire.
And the prompt does not engage in the message area. Of course, this is academic as you can't write a message anyway.
Also, PSE 11 doesn't work with Windows 8 and/or Outlook 2013 and Adobe doesn't seem to care. This is a step backwards in terms of compatibility. Frustrating that Adobe customer service doesn't care even though Outlook is an email option under preferences. Any ideas?
