User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3 Build Identifier: 4.42.0.0 and 1.8.20070.22120 1. cannot load so that proper mail boxes show..."names" given to each box at setup, do not correspond to that in the config file...I have to go in and hand alter the config file to redirect the mail to the correct box...now that does not even work e.g. I have three addresses...b1caez01@cogeco.ca [pop.cogeco-1.ca], b1cae02@ [pop.cogeco-2.ca], b1caez03@ [pop.cogeco-3.ca]. Mail for the 01 file ends up in Local Folders, that for the 02 file ends up in a file Thunderbird creates itself, e.g. [pop.cogeco-4.ca]; etc. So, I have to into the config file and lead the stupid mail to the correct stall. Now, I cannot even manage that. 2. when it was working, it would often appear to show mail in a box, but once the whole mess loads, that mail has vanished...and no prog has managed to reclaim it...I'm losing a lot of valuable correspondence. Reproducible: Always Steps to Reproduce: 1. over time it has ground to a halt 2. 3. Actual Results: I have deleted and reinstalled Thunderbird many times. I have even reformatted the hard drive many times. And I've used various versions. All of this has only recently begun to show itself...I'd say, over the last few months. Expected Results: I'm an old timer, and cranky! ...and have been working with my computers since the early '90s...so you'd think I'd learn a thing or two... This whole mess could be cleared up by having at least two different config files...one specifically for mail setup, similar to what you have now, and one specifically for environmental parameters setup...i.e. don't have the account parameter setup routine go anywhere near the other. That setting up of a new account routine should be isolated from the any other part of the program.

hard to understand your problem, in part because you describe two or more issues at once, which we don't generally do. see https://bugzilla.mozilla.org/page.cgi?id=bug-writing.html Going to assume your dataloss is more important to you. have you consulted links at http://en-us.www.mozillamessaging.com/en-US/support/ or kb.mozillazine.org? can you post your build from help>about?

Reporter can answer to comment #1? Another question: you have an antivirus? If the answer is yes and you have unchecked the option "Allow antivirus clients to quarantine individual incoming messages", you see anithing quarantined in your antivirus?
