Description

[Henning]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.1) Gecko/20090616 Firefox/3.5 (.NET CLR 3.5.30729)
Build Identifier: Thunderbird 2.0.0.22

After upgrading Thunderbird 2.0.0.21 to 2.0.0.22 the right-click options on files like pics, docs, etc. with "sent to --> email" always tries to open MS Outlook. We checked: Thunderbird is standard e-mail software so that seems not to be the cause. This problem occured on 3 of 3 Windows Vista Ultimate Service Pack 2 PCs after the upgrade to 2.0.0.22. 

Scenario:
- Open windows explorer (for files, not IE)
- Choose e.g. jpeg or doc
- right click on file and choose "send to --> email"
- function will either not work, open MS outlook or if you open ms outlook the composition window of ms outlook will appear insteadt of Thunderbird


Reproducible: Always
