Hhmmm. I have an interesting problem. Fortunately it is cosmetic (i.e. things works and no data loss) but it is quite annoying (and confounds my mail flow).
I'm running 6.2b1 on latest OS 10.8.4 with all updates. The issue I'm seeing is with new incoming messages. It certainly happens with IMAP which is where most mail arrives (i.e. iCloud). I might happen with POP3 but I get so little mail that way that I can't be sure. Maybe, maybe not. I have preferences set to enable HTML, but the setting to prefer it is NOT enabled. That is, if mail has both HTML and text, I want text. What I'm seeing is that when I click on a message in Mail Browser, the text displays for a very brief time (1/4 second or so) and then disappears. This happens with text-only and text+html messages. The PM "envelope" icon is only half-there, seemingly indicating that the message is not available (only the RFC822 header is shown). But the message *did* appear for a brief time. Clicking on another message and back again does not seem to help. Clicking on another mailbox and then back to InBox does cause the message to show, as text. At the third try, selecting another message and coming back did get the message content to display (previously it was just the RFC822 header, as I have show-full-headers enabled). The message had text/plain and text/html parts. A second message with the problem was text/plain with quoted-printable encoding. A third was text/plain, 7bit. I am not certain that this change came with version 6.2b1. It might have been earlier but hasn't been there long. Has anyone else observed this ? Thanks.....Peter
