I'm not getting any errors or warnings as far as I can tell, and I don't think the UIDs are changing unexpectedly -- messages are not getting re-downloaded randomly. That is, everything SEEMS to be working fine, as far as I can tell. So many people still use mbox that I hope we can fix this issue. I'm happy to help test or provide further debug output... this problem is certainly reproducible here, and it seems like lbutlr has a similar problem, so hopefully we can address at least this one... (I'm also happy to give you the Junk mailbox and index files... there's nothing sensitive in my spam!) Cheers. --- Amir
