I don't understanbd of this but I have download 4.80 but the spell checker does not accept new words: I can't add to the disctionary.
Some months ago I get a message from Mr Harris saying Pegasus was aware of the fault and was 'fixing it'.
Has it been fixed? How do I get the repair?

It's fixed in the 4.81 public beta. Goto https://pmail.com and look for the public beta.

Wait for the next version of the beta. The current one is undergoing revisions to fix an issue with disappearing POP3 and SMTP definitions. Release goal is a few days.

Note: You will need to find a backup of your USRDICT5.PMD file, since a bug was causing all the added words to be deleted. So, previous solution was to restore a backup of file, and then make the file read-only so it wouldn't get blanked out. But once a fixed version is installed will have to remove the read-only to be able to add new words.
