Thank you! That took care of it.

After successfully sending out a couple messages today, Pegasus suddenly crashed. After re-opening it, everything works fine except my sending capability. The queue status indicates 7 messages queued. I open the queue manager, delete the 7 "messages" all of which are 0.0k, but after closing that window, the "queued messages" continue to appear. I can't delete them. I've tried this several times, closing the program, deleting the queue, but they persist.

 I am running 4.70, and just realized I need to upgrade my version. Seems funny things were working fine this morning, then poof--- not.

I don't know the details of what causes these zero length queued

messages or why they won't delete by normal means but the solution is to delete the zero length .PMO, .PMX and .PMW files in your Home mailbox directory.  

If you don't know the location of your home mailbox directory go to Help | About Pegasus Mail then click the Info button.
