I'm using Thunderbird 1.0 (20041206) with 9 email accounts configured and around 50 folders and subfolders under "Local Folder". I use the toolbar's "next" button to read my messages. After i read the last unreaded message in any folder, i click "next" button and it asks me if i want to advance to next unread message in ???? folder. I click "OK", the window close and nothing happens. Then i immediately click on "next" button again, it asks, again, if i want to advance to next unreaded message in ??? folder. I click on "OK" and now i go to next unreaded message in ??? folder.

this works for me - when you say ???? and ???, you mean the same folder, right? Is it possible that the summary file is missing or out of date for the ???? folder? Does this happen all the time, or just sometimes?

No, different folders. I'll try to explain again. I'm reading mail from folder "a" and, using the "next" button, reach the end of unreaded messages. Then i click "next" button and the window opens asking me if i want to advance to next unreaded message in folder "b". I click "Ok", the window closes and nothing happens. Then i click "next" button again and now i go to folder "b", in the first unreaded message. I'm sure that the summary file is not missing and it is up to date. This happens every time i reach the end of unreaded messages in a folder and still have messages unreaded in another folder.

This bug is also affecting me. I'm using Thunderbird 1.0.2 (20050317) on Windows 2000 SP4. I originally thought this problem *might* have been caused by an extension I had, but after disabling all extensions by running Thunderbird in Safe Mode with this profile, this problem still exists: If I'm reading a message in one folder, and have an unread message that's in a different folder, I have to click twice on the "Move to next unread message" button (as the first click does nothing) in order to go to the unread message in the other folder.

This bug affects me as well. I use Thunderbird 1.0.6 on Windows XP. I have a total of 4 incoming mail folders in Thunderbird. This problem occurs when I open the first unread message in a separate window and then advance through the next unread messages with either the space bar or the "n" key. This problem does _not_ occur when I advance through the unread messages in preview mode (three-pane view). This difference in behavior between three-pane view and full-window view may explain why not everyone was able to reproduce this bug.

Resummarizing; confirming based on bug I'm about to dupe here.

Also a bug for me. XP Pro, Thunderbird 1.5.0.2. After reading all messages in folder, I press "n" (BTW this of course only works on lower-case "n", never for upper-case, which could be fixed!) and am asked to advance. I press Enter key, and nothing happens. I press "n" again and am asked, and press Enter, and this time, it goes to next unread message in whatever folder is next. Reproduceable: always happens this exact way! Peter Brown peterbbrown@charter.net

There is a partial workaround: add user_pref("mailnews.nav_crosses_folders", 0); to prefs.js or user.js in the Thunderbird profile directory. This advances to the next folder unconditionally, i.e. you get no prompt instead of two prompts. Not ideal, but not quite as irritating.

(In reply to comment #8) > There is a partial workaround: add > > user_pref("mailnews.nav_crosses_folders", 0); > > to prefs.js or user.js in the Thunderbird profile directory. Actually, space or 'n' is still ignored the first time you cross folders; it's just that you get no prompt on either the ignored keypress, or the keypress that works.

I don't see this problem any more in Thunderbird 2.0.0.4. Is it completely fixed?

I'm going to take David's word on this and resolve as WORKSFORME. If anyone can still reproduce in Thunderbird 2.0.0.x, please reopen.
