User-Agent: Opera/9.80 (Windows NT 5.1; U; en) Presto/2.2.15 Version/10.10 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.5) Gecko/20091204 Thunderbird/3.0 TB/SM will create two mails with the same file if you attach a file by clicking on it with the right mouse key and the "Send to => E-Mail receiver" and if you repeat this with another file which is in a different folder but has the same name. Reproducible: Always Steps to Reproduce: 1. Create two different files in two different Folders but use the same name (e.g. c:\temp\file.pdf and c:\other_directory\file.pdf 2. Click on the 1st file with the right mouse key and say "Send to => E-Mail" 3. Click on the 2nd file with the right mouse key and say "Send to => E-Mail" Actual Results: Two messages editors will be open but both contain the same file. You don't really noticed that the wrong file is attached unless you try to open the file. Expected Results: Either: The message editors should contain the two different files you actually wanted attachted. Or: You could solve it like Outlook. If one message editor is already open and you do exactly the same, there is a message like "Message window already open, please close it before starting a new mail". Three Notes: 1. This also happened with Tunderbird 2.x and Seamonkey 2.0. 2. I use the German language Windows version where the rightklick means "Senden an => Email-Empfänger", not sure if it is called "Send to => E-Mail receiver" in the English version, but I think so. 3. Also the Subject if you do this is nonsense, it says: "Senden an: file.pdf" (Sending to: file.pdf), which is nonsense because you do not send this to someone called file.pdf.

> 3. Also the Subject if you do this is nonsense, it says: "Senden an: file.pdf" This is probably a localization problem. In English version of Thunderbird, the subject is "Emailing: file.pdf" which makes enough sense.
