I use message filtering to filter incoming mail from IMAP into local mail folders on Mozilla 1.0. Using the 3-pane layout and 'n' keyboard shortcut to read mail, the first mail always shows up blank in the preview pane when changing from 1 local folder to another, but the mail is marked read. Steps to reproduce: 1. Create 2 local folders and put messages in them. 2. Mark 1 message in each folder as unread. 3. Go to the first folder, click on the first unread message in headers pane so the body shows up in preview pane. 4. Press 'n' to go to next unread. 5. Dialog pops up, asking 'Advance to next unread message in <folder name>?' Answer OK. Expected result: Unread message in next folder is selected and its body is shown in preview pane. Actual result: Unread message in next folder is selected, but preview pane is blank. The message is also marked read. Selecting another message and back makes the body show up. This is always reproducible.
