does startin Tb in -safe-mode (http://support.mozillamessaging.com/en-US/kb/Safe+Mode) helps ?

Comment 2

[Chris McFarling]

Starting in safe mode does not keep this from happening. It happens when TB is launched and it also happens if I open a folder in a new window (ex. control+click on INBOX and select Open from the contextual menu).

What is the value of HKEY_LOCAL_MACHINE\Software\Clients\Mail on your machine ?

Ok I've set mail.app as my default client. Unchecked the check at startup and I wasn't prompted , so I cannot reproduce with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.11) Gecko/20101013 Thunderbird/3.1.5.

Some thing is playing tricks. What's the default mail client ?

I've done some more testing and this is what I've determined...
1) Create new profile
2) Start TB using new profile
3) Mail Account Setup window is displayed
4) Since we're just testing, Cancel out of that window
5) 'Use Thunderbird as the default client' panel is displayed
6) **Here's the catch...  Click Cancel
7) Go to Preferences
8) Deselect 'Always check to see if Thunderbird is the default mail client on startup' (should already be deselected)
9) Quit/relaunch TB
10) 'Use Thunderbird as the default client' panel is still displayed despite the preference setting that instructs the program not to display it.

Apparently until you click OK from the 'Use Thunderbird as the default client' panel the app will display the panel no matter what. In essence you're forcing the user to click OK in that panel. Until the OK button is clicked then the application preference setting is irrelevant. It seems to me that app pref setting should take precedence.

If step 6 is the problem here then see bug 476426.
