Unable to Print Emails With .PNG Attachments in Windows Live Mail 2012

I have an end user who is running Windows Live Mail (WLM) 2012.  Whenever this user receives an email with a .PNG attachment, he is unable to print the email.  If he clicks on the Print button in WLM, nothing happens.  There is no error message generated.

If the user then clicks on Forward and saves the email in the Drafts folder, then he will be able to print the email.  This is a very strange problem.

I found the following community post which seemed to describe a similar issue:

The Microsoft Forum Moderator suggested updating to WLM 2012.  In my case, the user is already running WLM 2012.

Here are my questions:

1) What troubleshooting steps should I try to identify the cause of this issue?

2) What is the recommended resolution?
