Reproducible: Always Steps to Reproduce: 1. Set view to unread only on a mailbox (view... threads... unread) 2. Set "Compact folders when it will save over " to a small number and enable (the problem didn't seem to occur when using a manual compact). 3. POP some messages to the box and delete them (I used shift delete). 4. Thunderbird should compact the mailbox and lose the view settings. Actual Results: Thunderbird should compact the mailbox and lose the view settings. Expected Results: View settings should not be affected by a compact. This has happened on both Thunderbird 3.0 release and the nightly build I am currently running.
Was it happening in version 2 ?
I never had this problem in V2.
this is fundamentally a compact issue which has always exist, but the compacts mighit be happening more frequently in v3.
Perhaps rkent recalls the bug which may have fixed this. If not, Randy's address bounces and a similar bug  recently closed as WFM. So, with no other reporters and steps which no longer reproduce the issue, closing incomplete.  Bug 509042 Summary: Junk, Sent, and Trash Folders Occasionally Lose Sort Order and Retention Policy Settings after auto-compact
I don't know why your email to me was bouncing, but I received an email of this status update. I tested the problem and it no longer seems to occur. Thanks! Randy
Randy, thanks for the update
