SMTP Control 0.6.0rc1 (Realease Candidate 1) is now available to correct the bug with SMTP selection.
You can find it here :
http://www.phpconcept.net/smtp-control/smtp-control-downloads

I will publish it on Mozilla web site as soon as I can, and then there will be a delay before the approval for publication.

Sorry for this bug, due to a change in some attribute value in message composer window.

Please let me know if you find an other abnormal behavior.
