Thanks for your suggestion.  It might work - however, I'm not quite sure I understand exactly how you'd copy a message from an old mailbox into a new one on a freshly installed Pegasus.  Do you knnow of a place in Pegasus which would permit me to browse for the old Mail folder containing the old mailbox?

I've not followed up on my posts and the great help I was receiving from Thomas because I decided to upgrade my computer and thought a fresh install would do the trick.  The computer is now built and  I've successfully installed version 4.5.0 (beta) on the 64bit o/s. 

Then, using the charts on "Han's" web site, I copied over all my

folders (leaving duplicate copies behind), my address books and

Distribution lists, and my signature files.  I felt that by doing it

this way, rather than copying everything over, I might eliminate the

problem that first brought me here over 2 months ago.  It didn't....   I still can't do a

"save copy" with specific letters.  I've tried saving to different

folders, I've tried making new folders, I've tried deleting old folders

and replacing them with new ones.  Still, for some strange reason, I'm

unable to save some letters (for example, if I try to keep a copy of a

letter I send to my daughter it won't accept it so I have to mail a

copy to myself and then move it to the designated folder) - - but, if I go to the "Review Queued Mail" tray before sending the letter out, I can then save a copy to the very same folders that it won't go to when I tried earlier..

NEW problems have since developed:

The "Open or Rescan Your New Mail Folder" button is inactive.

The option to have mail that I've read moved from the "New Mail" folder to the special "New Mail" folder (created by Pegasus during the installation process), suddenly stopped working and, instead, the read mail was being deleted from the main New Mail folder (I stopped this from happening by clicking the "All read messages......" button in the settings folder.

When Pegasus first opens, and the New Mail folder opens, I've got it set to automatically check for new mail.  It won't.  I've got to click the "Check your pop3 host for new mail" button.

Since I've done a completely clean re-install on a brand new hard drive, and I then made sure that nothing was duplicated in the copying over of old files (I didn't replace any of the newly installed program files), I'm still asking the question: Is it me, or is it a bug in 4.5 beta??

Thanks again for your earlier help, your patience and, hopefully, upcoming help.

Have you tried doing a completely clean install and then, instead of copying over your original files into the new installation, just connecting to the old mailbox and copying across the messages into new folders - you know, as if you were just shuffling messages from one folder to another?

By not copying across your potentially-corrupt folder files (PMI,PMM), and only the messages within, you may be OK. You would have to recreate signatures and check the program options are as you want them, but I suspect that if everything seems fine, you could just copy your addressbooks normally. Filtering rules I would probably recreate too.
