Bugzilla

Thanks Mitra, nice move!
I would hope/suspect that problems with automatically getting messages are *not* caused by the Supernova 3-pane UI, so this might be a pre-existing problem. I believe there's a similar bug on record which I can't find right now.

I'm surprised at your summary, `"Getting all messages" stops happening automatically`, which may be based on a misconception:
Thunderbird does not have a feature (yet?) to "Automatically check for new messages on **all** accounts every nn minutes" (as if you were pressing the `Get [all] messages` button every nn minutes`). Instead, checking for new messages automatically is based on the respective **per-account** pref labeled `Check for new messages every xx minutes`. You may have different checking intervals for different accounts of yours, and (hopefully) those would all be honored.

- Which account types are affected? (POP/IMAP)
- What's your `Check for new messages every xx minutes` setting on the failing accounts?
- Does this happen when TB sleeps in `≡ > Help > Troubleshoot Mode…`?
- When this occurs, does your OS sleep (PC remains on) or hibernate (suspend to disk)?
