User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:184.108.40.206) Gecko/2009032609 Firefox/3.0.8 Build Identifier: version 220.127.116.11 (20090605) My problem is related to the function in Windows XP which allows the user to send a file via email from anywhere on the computer by 'right clicking' then selecting 'send to' -> 'email recipient'. This function was working correctly and allowed me to quickly attach a file to a new email within Thunderbird, when Thunderbird was running in the background. Following the automatic update to 'version 18.104.22.168 (2009060502)' this functionality ceased working. The option to 'send to' -> 'email recipient' is still present in the right click menu, but Thunderbird no longer responds to this command by opening a new email and attaching the specified file. Reproducible: Always Steps to Reproduce: 1. right click file desired to be attached to email anywhere in windows explorer. 2. select 'send to' -> 'email recipient' 3. new 'compose' email window should appear with file attached... no longer does. Actual Results: Unable to quickly attach file to new email. Must first bring up Thunderbird, open new email, hit attach but etc... slowed work process and reduced convenience is the result. Expected Results: Nothing happens. No window appears. If a .jpg file is 'sent to email recipient', a window appears offering to resize image or leave as current size. Following selection, nothing further happens. The compose window does NOT appear.
