Created attachment 581286 [details] aoperacaofalhouporqueoutraestausandoapasta.png User Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; pt-BR; rv:188.8.131.52) Gecko/20111103 Firefox/3.6.24 Build ID: 20111103063747 Steps to reproduce: Opened the thunderbird version 184.108.40.206 (20090812) in MAC OSX. Actual results: Before retrieving and showing any new messages from smtp server, thunderbird imediately pops this "attention" message on screen and requires dismissing its window to continue working. The entire message is "A operação falhou porque outra operação está usando a pasta. Por favor, aguarde pelo término da operação e tente de novo" which in english is like "the operation failed because another operation is using the folder. Pleasel, wait for the end of the operation and try again". This bug exists for years now, it is not new, no one has solved it. Clearing msf files, condensing folders and similar things are void. The big problem starts with the error message which is meaningless itself. Expected results: Thunderbird should have retrieved the messages from the smtp IMAP server normally instead of bugging us with a message which does not say anything useful. There is no sense in waiting the end of an operation which we don't know what it is. In other words, the error message does not say what kind of operation is causing the problem. Additionally, there is no sense in "waiting the operation to end" because there is no activity shown, we don't know what the software is trying to do to predict how long it will take, it does not tell where it encounters problems, and so we don't know what to wait for. By pressing enter to dismiss the message, another one will come in less than a second, and again, and again, it will stop in every new message it finds in the smtp server.
Sorry, but I really doubt anything will be done for Thunderbird 2. Are you able to move to TB 8 or later? MANY problems are fixed there.
Sorry, but Thunderbird 2 hasn't been supported for over a year now, and 220.127.116.11 is about 2 years old. If you are able to reproduce this on the latest version of Thunderbird, please feel free to re-open.
The issue with this message is still not solved in TB 24: https://bugzilla.mozilla.org/show_bug.cgi?id=988792
