With Pegasus Mail closed, use a file explorer to navigate to your home mailbox directory then look for a file with a .PMO extension.  These are auto-saved, draft, or stationary messages.  Move it out of the directory for future deletion once the problem is solved. There may be a corresponding .PNX file if an RTF version was saved.  Remove it as well.  

In the event you have multiple .PMO files and know some are stationary that you wish to keep you can open them with a text editor.  The content should be enough to tell you what they are but if not, look at the SY: entry.  SY:1 indicates stationary.

I evidently have an "auto-saved" message thats causing an issue.

Starting Pegmail it works fine then comes up with  "Pegasus has found one or more auto-saved messages and to continue editing them click on the open button below"...

If I click on the open button for a moment the autosaved message comes up but after that it causes the Pegmail program to crash. 

If I click on the continue button it works fine but am getting tired of going through this. How can I delete the auto-saved message without clicking on the "open" button?  

 Thanks!
