I have installed Desktop Home 10.1.1 to my Windows 7 64-bit system. I have three mailboxes, one with my direct ISP, and two associated with domains I own via Go-Daddy. PGP will encrypt emails sent from my ISP mailbox, but will not encrypt emails sent from either of my domain mailboxes. It does not give an error message; it just sends the email in the clear without encrypting. When I try to force encryption by putting PGP in the subject field, it is supposed to halt with a dialog if it does not find a public key, but it does not halt, does not give a dialog, and does not encrypt. All three of my email addresses have been added to my keypair. For testing purposes, all my emails so far are being sent to myself, either to the same email address or one of my other email addresses. The above description is consistent regardless. Nothing I do seems to make any difference.
