And at first look if there is any *.cnm file having 0 bytes - this one you surely can delete safely! The others *.cnm move somewhere instead of raw deleting - you may want to get them back.

I sent a email from Pegasus 4.52 and it did not go.  When I try to open Pmail I get a dialog that says it appears to be locked by another process.  I hit continue and them get a box that says it has stopped working and has to shut down. Help is appreciated.  I am using Win 7 Ultimate.  TIA

Have you tried the standard method of removing all of the .cnm files from your mailbox to see if the problem is one of the new messages in your inbox?
