After removing all CNM files, I re-opened Pegasus.  Discovered that the install had succeeded and that I had version 4.63.  So, having checked the suggested post again (this time I could actually see it, for Pegasus opened), I looked.  No such option is present there.  Might there be another way of obtaining that file?

OK, did the  "strip out CNM files and replace in batches".    As I did, I kept my eye on one very large file, and didn't install it, watched Pegasus start up each and every time..  When all but that were returned, I tried to open that file (105,609KB worth)  from the temp folder I had stashed 'em all in.  It eventually opened in Notepad.  It turned out to be a post that had bounced (my ISP is now "powered by Google") because it exceeded Google's message size limit.  So it contained both the large tif and jpg that went out in the original post plus the extra guff that my ISP added, plus Pegasus' bounce message.

So there's the secret:  Pegasus really does not like really big new mail files ... and even letting it stew overnight, it still doesn't like them.  Now I know what to look for.

Size is probably not the issue.  You should forward the cnm file for examination as requested.

Yup.  I've read the "crashes, hangs ..." links.  No joy.

When called, it first tells me that the mailbox is locked because another might be using it.  Well, they're not.  So I hit 'continue' and gets to 'opening new mail folder' and hangs.  When I kill it, XP tells me it ain't responding and:  

 szAppName : winpm-32.exe     szAppVer : 4.6.3.0     szModName : hungapp    

szModVer : 0.0.0.0     offset : 00000000  

C: \DOCUME~1\GENERA~1\LOCALS~1\Temp\WERf8c1.dir00\winpm-32.exe.mdmp

C:\DOCUME~1\GENERA~1\LOCALS~1\Temp\WERf8c1.dir00\appcompat.txt

So I then downloaded the most recent versh (4.63) and, get the same result.

 I've searched the several relevant threads in the forum, and one tells me to take out the cnm files.  Well, there are a ton of cnm files, and so I am reluctant to do so.

 Any other ideas?   Thanks in advance.

Cnm files are new message files and it is possible that one of those messages is causing Pmail to crash.

It is worthwhile removing them regardless of the number and putting them back in batches to pinpoint the problem message.
